With respect to the reflecting surface.

With respect to the direction of wave propagation.

With respect to the incident ray.

A wave is generated in a ripple tank. If the frequency of the vibrator is increased while the depth of the water remains constant, what happens to the wavelength and the speed of the wave?

Wavelength decreases, speed decreases.

Wavelength increases, speed increases

Wavelength decreases, speed remains constant.

Wavelength remains constant, speed increases.

None

9.

Diffraction

Reflection

Refraction

None of these phenomena change the frequency.

10.

A sound wave is an example of a longitudinal wave. This means that the particles of the medium vibrate…

in circular paths, creating peaks and troughs.

only when the wave passes from one medium to another

parallel to the direction of energy transfer.

perpendicular to the direction of energy transfer

None
