Light and Color and Refraction

Front

What is the RGB color model used for?

Back

The RGB color model is used for electronic displays, such as cell phone screens, where colors are created by combining red, green, and blue light.

Front

What is the index of refraction formula?

Back

n₁sin(Θ₁) = n₂sin(Θ₂), where n is the index of refraction and Θ is the angle of incidence or refraction.

Front

Which color in the visible spectrum has the highest energy?

Back

Violet has the highest energy in the visible spectrum.

Front

Which color in the visible spectrum has the lowest energy?

Back

Red has the lowest energy in the visible spectrum.

Front

What happens to frequency as we move from infrared light to gamma rays?

Back

The frequency increases as we move from infrared light to gamma rays.

Front

What is the index of refraction of air?

Back

The index of refraction of air is approximately 1.00.

Front

What is the relationship between wavelength and energy in the electromagnetic spectrum?

Back

As wavelength decreases, energy increases; shorter wavelengths correspond to higher energy.

Front

What is refraction?

Back

Refraction is the bending of light as it passes from one medium to another due to a change in speed.

Front

What is the visible spectrum?

Back

The visible spectrum is the portion of the electromagnetic spectrum that can be seen by the human eye, typically ranging from 380 nm (violet) to 750 nm (red).

Front

What is the formula to calculate the index of refraction of a material?

Back

n = c/v, where n is the index of refraction, c is the speed of light in a vacuum, and v is the speed of light in the material.
