What is a key characteristic of transverse waves?

• Particles move parallel to the direction of wave propagation.

• Particles move perpendicular to the direction of wave propagation.

• Particles do not move at all.

• Particles move in a circular motion.

Which of the following is a characteristic of longitudinal waves?

• They can only travel through solids.

• Particles move perpendicular to the direction of wave propagation.

• Particles move parallel to the direction of wave propagation.

• They do not require a medium to travel.

What is the primary application of sonar waves?

• Measuring temperature.

• Navigating and detecting objects underwater.

• Communicating with satellites.

• Generating electricity.

Which property of sound waves determines the pitch of the sound?

• Amplitude

• Frequency

• Speed

• Wavelength

How is the speed of a wave calculated?

• Speed = Frequency × Wavelength

• Speed = Wavelength / Frequency

• Speed = Frequency + Wavelength

• Speed = Frequency - Wavelength

If a wave has a frequency of 10 Hz and a wavelength of 2 meters, what is its speed?

• 5 m/s

• 10 m/s

• 20 m/s

• 30 m/s

What is the time period of a wave with a frequency of 5 Hz?

• 0.2 seconds

• 0.5 seconds

• 1 second

• 2 seconds

Which of the following is true about the wavelength of a wave?

• It is the distance between two consecutive crests or troughs in a transverse wave.

• It is the time taken for one complete cycle of the wave.

• It is the number of waves passing a point per second.

• It is the height of the wave from the rest position.

In which medium do sound waves travel the fastest?

• Air

• Water

• Vacuum

• Steel

If the speed of a wave is 300 m/s and its frequency is 50 Hz, what is its wavelength?

• 2 m

• 4 m

• 6 m

• 8 m
