What does the law of reflection state?

• The angle of incidence is greater than the angle of reflection

• The angle of incidence is equal to the angle of reflection

• The angle of incidence is less than the angle of reflection

• The angle of incidence is unrelated to the angle of reflection

What happens to a wave when it is refracted?

• Its frequency changes

• Its wavelength remains constant

• Its speed changes

• Its amplitude changes

What is diffraction?

• The bending of a wave when it travels around a body or through an aperture

• The reflection of a wave at a boundary

• The absorption of a wave by a medium

• The transmission of a wave through a medium

What does the refractive index of a medium measure?

• The amplitude of light in the medium

• The frequency of light in the medium

• The wavelength of light in the medium

• How much the medium can slow down light

What does Snell's law describe?

• The relationship between the amplitude and wavelength of a wave

• The relationship between the angle of incidence and the angle of reflection

• The relationship between the speed and frequency of a wave

• The relationship between the angle of incidence and the angle of refraction

What is the critical angle?

• The angle of incidence that results in maximum reflection

• The angle of incidence that results in total absorption

• The angle of incidence that makes light refract along the boundary between two materials

• The angle of incidence that results in no refraction

What occurs when the angle of incidence is greater than the critical angle?

• Partial reflection

• Total internal reflection

• No change in the wave

• Complete absorption

What happens when two waves superpose?

• They remain unchanged

• They always cancel each other out

• They can constructively or destructively interfere

• They always amplify each other

What is required for a clear double-source interference pattern?

• The two sources need to be out of phase

• The two sources need to have different amplitudes

• The two sources need to be coherent

• The two sources need to have different wavelengths

What is Young’s double-slit interference?

• A series of light and dark fringes produced by shining monochromatic light through two slits

• A single bright spot produced by shining light through a single slit

• A pattern of concentric circles produced by shining light through a circular aperture

• A uniform light pattern produced by shining light through a prism
