Refraction

Which is more dense?

If light passes from water to air, which of the following gives a good value for the angle of incidence if the angle of refraction is 40 degrees?

A student placed a pencil in a cup of water. The pencil appears broken because light

Based on the image, which medium has a larger index of refraction?

When light passes at an angle to the normal from one medium into another in which its speed is higher

Light travels from air (n = 1.00) into a "mystery" material. The incident ray of light hits the surface at angle of 43^o and the refracted ray enters the mystery material at an angle of 27^o. What is the index of refraction of the mystery material? n₁sin(Θ₁) = n₂sin(Θ₂)
