Wave Behaviors Quiz

What is the law of reflection?

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

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

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

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

What causes refraction of waves?

• Change in wave direction due to obstacles.

• Change in wave speed due to different media.

• Change in wave amplitude.

• Change in wave frequency.

How does a prism create a rainbow?

• By bending light waves at different speeds.

• By absorbing certain colors of light.

• By reflecting light at different angles.

• By scattering light in all directions.

What is diffraction?

• Waves bouncing off a surface.

• Waves bending around an object.

• Waves being absorbed by a material.

• Waves combining to form a new wave.

Which type of wave is more prone to diffraction?

• Microwaves

• Radio waves

• Sound waves

• Light waves

What happens during wave absorption?

• Waves increase in amplitude.

• Waves are reflected back.

• Waves pass through without change.

• Waves are absorbed and converted to thermal energy.

What is constructive interference?

• Waves decrease in frequency.

• Waves cancel each other out.

• Waves add together to increase amplitude.

• Waves pass through each other without interaction.

What is a standing wave?

• A wave that travels in a single direction.

• A wave pattern that appears stationary.

• A wave that changes amplitude.

• A wave that moves continuously.

What is resonance?

• An object vibrating at a random frequency.

• An object vibrating at its natural frequency by absorbing energy.

• An object vibrating without any external influence.

• An object vibrating due to external force.

How do tuning forks demonstrate resonance?

• By creating standing waves.

• By vibrating at their natural frequency.

• By reflecting sound waves.

• By absorbing light waves.
