Physics Quiz on Refraction and Snell's Law

What happens to light when it hits a piece of glass head on at an angle of incidence of zero degrees?

• It scatters

• It passes straight through

• It reflects

• It bends

What is the term used to describe the bending of light as it passes through different materials?

• Diffraction

• Reflection

• Refraction

• Dispersion

What is the angle called that is drawn at 90 degrees to the surface where the light ray meets the boundary?

• Critical angle

• Normal

• Angle of refraction

• Angle of incidence

What do we call the ray of light that comes in and hits the surface?

• Incident ray

• Refracted ray

• Reflected ray

• Normal ray

What is the relationship between the sine of the angle of incidence and the sine of the angle of refraction?

• They are unrelated

• They are proportional

• They are equal

• They are inversely proportional

What is the constant called that is equal to the sine of the angle of incidence divided by the sine of the angle of refraction?

• Refractive index

• Incident index

• Normal

• Critical angle

What is Snell's Law used to describe?

• Diffraction of light

• Reflection of light

• Refraction of light

• Dispersion of light

How is the refractive index of a medium defined in terms of the speed of light?

• Speed of light in vacuum divided by speed of light in the medium

• Speed of light in the medium divided by speed of light in vacuum

• Speed of light in air divided by speed of light in the medium

• Speed of light in the medium divided by speed of light in air
