Question 1: Which of the following is a property of waves?

Answer: Wavelength

Question 2: What is the speed of a wave with a frequency of 50 Hz and a wavelength of 6 m?

Answer: 300 m/s

Question 3: True or False: Sound waves can travel through a vacuum.

Answer: False

Question 4: Define the term 'frequency' in the context of waves.

Question 7: Fill in the blank: The _______ of a wave is the distance between two consecutive crests.

Answer: wavelength

Question 8: True or False: Light waves require a medium to travel through.

Answer: False

Question 9: Explain how the frequency and wavelength of a wave are related, given a constant wave speed.

Answer: At a constant wave speed, frequency and wavelength are inversely proportional.

Question 10: A wave has a frequency of 500 Hz. Calculate its wavelength if the speed of sound in air is 340 m/s.

Answer: 0.68 m

Question 11: Discuss the differences between transverse and longitudinal waves, providing examples for each.

Answer: Transverse waves have oscillations perpendicular to the direction of wave travel; examples include light waves. Longitudinal waves have oscillations parallel to the direction of wave travel; examples include sound waves.

Question 12: What is the effect on the wavelength if the frequency of a wave doubles, assuming the speed remains constant?

Answer: The wavelength would halve.

Question 13: Multiple choice: What is the unit of frequency?

Answer: Hertz

Question 14: Multiple choice: Which type of wave is sound?

Answer: Longitudinal
