Resonance occurs in a system under forced oscillation when…

the amplitude of the oscillation is gradually decreasing to zer

the system is oscillating in a vacuum, preventing any damping.

the driving frequency is much higher than the natural frequency

the driving frequency matches the system’s natural frequency

None

Ultraviolet

Gamma rays

Microwaves

Infrared

None

Destructive interference occurs when two coherent waves meet at a point. This happens when…

the crest of one wave meets the crest of the other.

both waves are traveling in the exact same direction.

the trough of one wave meets the trough of the other.

the crest of one wave meets the trough of the other.

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 remains constant.

Wavelength decreases, speed decreases.

Wavelength increases, speed increases

Wavelength remains constant, speed increases.

None
