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 crest of one wave meets the trough of the other.

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

None

Speed

None

A displacement-time graph for a wave shows an amplitude of 5cm and a period of 0.4s. What is the frequency of the wave?

2.5 Hz

0.4 Hz

2.0 Hz

1.25 Hz

None

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

perpendicular to the direction of energy transfer

in circular paths, creating peaks and troughs.

parallel to the direction of energy transfer.

only when the wave passes from one medium to another

None

The Law of Reflection states that the angle of incidence (i) is equal to the angle of reflection (r). How are these angles measured?

With respect to the incident ray.

With respect to the direction of wave propagation.

With respect to the normal line.

With respect to the reflecting surface.

None

None

In the electromagnetic spectrum, which type of wave has a wavelength shorter than visible light but longer than X-rays?

Infrared

Gamma rays

Microwaves

Ultraviolet

None

What is the primary characteristic that distinguishes a mechanical wave from an electromagnetic wave?

Mechanical waves transfer matter, while electromagnetic waves transfer only energy.

Mechanical waves travel at the speed of sound, while electromagnetic waves travel at the speed of light.

Mechanical waves require a medium for propagation, while electromagnetic waves do not.

Mechanical waves are always longitudinal, while electromagnetic waves are always transverse.

None

The phenomenon of diffraction is most pronounced when…

the frequency of the wave is very high.

the wavelength of the wave is approximately equal to the size of the gap.

the amplitude of the wave is at its maximum.

the wavelength of the wave is much smaller than the size of the gap.

None
