What is the relationship between frequency and period?

• The period is the reciprocal of the frequency.

• The period is the square of the frequency.

• The period is unrelated to the frequency.

• The period is equal to the frequency.

What is the principle of wave reflection?

• The principle of wave reflection is that a wave disappears when it encounters a boundary or obstacle.

• The principle of wave reflection is that a wave changes direction when it encounters a boundary or obstacle.

• The principle of wave reflection is that a wave splits into multiple waves when it encounters a boundary or obstacle.

• The principle of wave reflection is that a wave bounces back when it encounters a boundary or obstacle.

What is wave refraction?

• The reflection of waves off a solid surface.

• The scattering of waves in different directions.

• The bending of waves as they approach the shore due to changes in wave speed caused by variations in water depth.

• The absorption of waves by a medium.

What happens to the speed of a wave during refraction?

• The speed of a wave remains constant during refraction.

• The speed of a wave increases during refraction.

• The speed of a wave changes during refraction.

• The speed of a wave decreases during refraction.

What is the effect of wavelength on wave diffraction?

• Shorter wavelengths result in more diffraction, while longer wavelengths result in less diffraction.

• Shorter wavelengths result in the same amount of diffraction as longer wavelengths.

• Wavelength has no effect on wave diffraction.

• Shorter wavelengths result in less diffraction, while longer wavelengths result in more diffraction.

What is constructive interference?

• Constructive interference is when two or more waves combine to create a wave with a smaller amplitude.

• Constructive interference is when two or more waves combine to create a wave with a larger amplitude.

• Constructive interference is when two or more waves cancel each other out.

• Constructive interference is when two or more waves change direction and travel in opposite directions.

What is destructive interference?

• Destructive interference is the combination of wave amplitudes resulting in a constant intensity.

• Destructive interference is the reflection of wave amplitudes resulting in a change in direction.

• Destructive interference is the cancellation of wave amplitudes resulting in a decrease or elimination of intensity.

• Destructive interference is the amplification of wave amplitudes resulting in an increase in intensity.
