Question

PART A

Snell's law describes the relationship between the angle a light ray makes as it leaves a surface, the angle it makes incident on the surface, and the indices of refraction on both sides of the surface. If light incident in air at angle of 30 degrees from the normal onto glass with an index of refraction of 1.5 --

Pick those answers that apply

		Inside the material, the light leaving the surface is closer to the surface, makes a bigger angle with the normal, than the entering light makes in air.
		The light inside the glass is closer to the normal, makes a bigger angle with the surface, than the incident light
		There is light reflected back into the air from the surface
		The angle is too steep for light to refract and it is all reflected.

PART B

Visible light with a wavelength of 546 nm (nanometers or 10^-9 meter) is green to the eye and is emitted by the mercury atoms in fluorescent lamps. How many times per second does the electric field of this light go through a cycle from maximum to maximum?

		5.49x1014 Hz
		1.83x106 Hz
		5.49x1012 Hz
		5.49x1016 Hz

PART C

Suppose that white light strikes a surface of flint glass at an angle of 60 degrees to the surface (30 degrees from the normal). The index of refraction of this dense glass for red light is 1.710, for green light is 1.723, and for blue light is 1.735. What is the order of colors you would see in the refracted light? In the reflected light? From the surface up --

Hint: In refraction, the ray deflected the most will be the one farthest from the surface as it leaves.

		Refraction: red green blue Reflection: blue green red
		Refraction: blue green red Reflection: all the same
		Refraction: red green blue Reflection: all the same
		Refraction: blue green red Reflection: red green blue

PART D

If the speed of light is nearly 3x10⁸ m/s in air (300,000 km/s), what is its speed in glass with index of refraction 1.5?

		200,000 km/s
		300,000 km/s
		450,000 km/s
		100,000 km/s
