Wave Properties Quiz

What type of waves have peaks and troughs?

• Longitudinal waves

• Transverse waves

• Sound waves

• Light waves

What is the frequency of a wave?

• The distance between a point on one wave and the same point on the next wave

• The number of waves that pass a single point per second

• The distance from the equilibrium position to the maximum displacement

• The time taken for one complete wave to pass a fixed point

What happens to the speed of a wave when it enters a denser medium?

• It increases and bends towards the normal

• It decreases and bends away from the normal

• It increases and bends away from the normal

• It decreases and bends towards the normal

What is the Doppler Effect?

• A change in the observed frequency and wavelength of a wave due to the motion of the observer

• A change in the observed frequency and wavelength of a wave due to the motion of the source

• A change in the speed of a wave when it enters a new medium

• A change in the amplitude of a wave over a period of time

According to the law of reflection, which of the following remains unchanged?

• Angle of incidence

• Angle of reflection

• Frequency, wavelength, and speed

• The medium through which the wave travels

How is the speed of a wave calculated?

• speed = frequency + wavelength

• speed = frequency / wavelength

• speed = frequency x wavelength

• speed = wavelength / frequency

What is the unit of frequency?

• Meter (m)

• Second (s)

• Hertz (Hz)

• Newton (N)

What remains the same for all electromagnetic waves traveling in a vacuum?

• Wavelength

• Speed

• Frequency

• Energy

In the electromagnetic spectrum, as the wavelength decreases, what happens to the frequency?

• It stays the same

• It decreases

• It increases

• It becomes zero

Which part of the electromagnetic spectrum is used in cooking and satellite transmissions?

• Radio waves

• Microwaves

• Infrared radiation

• X-rays
