Light changes direction when it goes from an area of lesser resistance (air) to an area of greater resistance(the glass of the prism). the amount of change in direction is related to the energy level of the light. Blue light is a higher energy wave, so it is bent less. Red light is a lower energy wave, so it bends more. Each color of light has a different energy level, and so, is bent more or less than the others. The light exiting the prism is spread into energy 'bands' which represent what our eyes detect as colors.

The light is fractured to a certain extent that when freyed it will split apart but i am a 13yr old so i probably have virtually the same knowledge of this subject that you do.

Good

Hi,
a 6ya expert can help you resolve that issue over the phone in a minute or two.
best thing about this new service is that you are never placed on hold and get to talk to real repairmen in the US.
the service is completely free and covers almost anything you can think of (from cars to computers, handyman, and even drones).
goodluck!

A rectangular prism is a solid (3-dimensional) object which has six faces that are rectangles. It has the same cross-section along a length, which makes it a prism.

### Why is the colour in my photographs not printing as they are in my laptop I have added new inks and cleaned the printing heads

Anonymous, there's a whole science of "color management" that you've invoked. First, what you're seeing is truly caused by lack of "calibration" in any stage of your workflow.
Your camera takes pictures, and whatever colors it sees are what it sees.
Your monitor shows you colors, but there's no standard calibration involved.
Your printer prints colors, but it too isn't calibrated to any standard.\

Assume for a minute that your monitor is set up to be a little too dark. You edit the pictures, and lighten them up so they look ok on screen. Now, when you print the picture, it's too light.

I've had similar issues, and have ended up purchasing a monitor calibration tool (Color Munki Smile) to calibrate my monitor, software "Profile Prism" to calibrate my printer, and now the prints I get look almost exactly like what I see on screen...

### RCA rear projection tv picture bowed to middle. Red Green Blue colors have been seperated on screen.

If I had to guess I would say it's either the DLP chip or the prism. Simply put the lamp lights the DLP chip which directs the light into a prism and then onto the TV screen. The prism or prisms are responsible for aligning the colors correctly. The DLP chip is essentially a million little moving mirrors which direct light

If you're at all comfortable with electronics you might want to open the TV up to take a look. You might get lucky and find something obviously wrong with the TV. Sometimes adhesives melt and parts slip out of place. If your DLP chip is blown there isn't much you can do. You're probably right that this would cost a lot to fix and not be worth it.

### What is colour temperature?

Colour temperature. The higher the K number the more blue and brighter the glare. The lower the K number the softer the light and more pink in the colour. The light colour can be explained by use of a strip lamp, (flourescent lamp).
The warm white strip lamp used in offices have a temperature of 2500K. The new type "energy saving" lamps have a temperature of 2800K and are whiter and have more of the blue spectrum in them.
I hope that helps.

### I have a 102 mm Astro-Nova telescope 525 power by eduscience that shows everything upside down. Is there a retailer that sells the proper piece? I cannot get in touch w/ the eduscience website or phone...

All astronomical telescopes show the image upside down. It's tradition and there is a good technical reason for this, but you can get an "erecting prism" to make the image upright. This does not have to come from Edu-Science if your eyepieces are the standard size (1.25 inch outside diameter). If you search Amazon or eBay for "erecting prism" you will find a few available. You probably won't want to pay the prices though.

### Opengl code

OpenGL doesn't handle photonics or any other low-level physics - you'll either need a raytracer, such as POVRAY or Blender, or you'll have to write the physics yourself, to emulate light rays of varying colours (I recommend using a HSL colour space for your physics, only translating to RGB when rendering the frame).
The refraction of a ray at the interface of the prism and the "air" can be calculated using Index of Refraction, correction factor to account for different refraction dependent on frequency (Hue) and a random number generator to emulate slight scattering.

### The left side of the screen is blueish?

The blue or yellow haze problem in this projector is because of two factors. 1) Dust buildup inside the optics and 2) Fading colour filters used in the internal optical process.

Inside the projector the white light from the lamp is split into three distinct colours of red, green and blue. Each colour illuminates their own monochrome LCD. Those LCDs are mounted on a prism that combines the separate images and displays the result you see via the lens.

The optical process to split the light up inside the projector is fairly complex and involves many light filters and mirrors to direct the light to the appropriate lcds. Those filters and lenses accumulate dust and also fade over time due to heat and other environmental factors.

I know that sharp sells replacement filters at \$100 a piece. I do not know if Hitachi sells replacements.

To remove the dust and change filters you have to take apart the projector in a fairly complex way. I do not suggest that the average user do this. Good luck!

### Blue blob

Hello rivas_gab. Before I answeryour question let me explain a little how your tv works. You TV uses is a 3LCDtv that gets its picture from a lamp, the lamp produces a white light brighterthan the sun, the light goes through a square prism and is split 3 ways, eachgoing through a small LCD chip (blue, red & green). Then it travels troughthe light engine where the final picture is produced. The blue blobthat appears on the screen might be caused by one or two lcd chips that havestarted to get burn by the intense heat emitted from the light of the lamp. If that is theproblem you’ll have to replace the entire light engine, the other option isthat you buy the prism with the lcd chips, how ever that almost impossible becausenobody that I know sells them separately. If you decide tobuy, search buy part number, NOT model number, otherwise you’ll run the risk ofgetting non compatible parts. If you’re lookinga place to purchase look for dedicated tv part distributors (my personal recommendation:Discount-Merchant ). Happyhunting.
