Wave Interactions Quiz

What happens to a wave when it encounters a rigid barrier?

• It reflects back in the opposite direction.

• It speeds up and continues in the same direction.

• It gets absorbed by the barrier.

• It passes through the barrier.

According to the law of reflection, how do the angle of incidence and the angle of reflection compare?

• The angle of incidence is always greater.

• They are equal in magnitude.

• The angle of reflection is always greater.

• They are unrelated.

What causes a wave to refract?

• A change in the medium it travels through.

• A change in the wave's frequency.

• A change in the wave's amplitude.

• A change in the wave's wavelength.

What is diffraction?

• The bending of waves as they enter a new medium.

• The spreading out of waves after passing through an opening.

• The cancellation of waves when they meet.

• The increase in wave speed when energy is added.

What is the result of constructive interference?

• Waves pass through each other unchanged.

• Waves change direction.

• Waves combine to form a larger wave.

• Waves cancel each other out.
