Sound And Waves - SS1 Physics Past Questions and Answers - page 3
The distance a wave travels in one unit of time is called its:
Amplitude
Wavelength
Frequency
Speed
The formula for calculating the speed of a wave is:
Speed = Frequency × Wavelength
Speed = Wavelength × Period
Speed = Amplitude × Frequency
Speed = Amplitude × Period
Define wavelength, period, and speed of a wave.
Discuss the significance of wavelength, period, and speed in understanding and analysing different types of waves.
When a sound wave encounters a smooth, hard surface, what typically happens?
Reflection
Refraction
Diffraction
Absorption
What happens to the direction of a sound wave when it passes from one medium to another with different properties, such as from air to water?
Reflection
Refraction
Diffraction
Absorption
Which of the following best describes the bending of sound waves around obstacles or through openings?

Diffraction
Absorption
Which of the following materials is known to absorb sound waves rather than reflect them?
Glass
Metal
Foam
Water
Explain the process of reflection of sound waves. Include an example and discuss the factors that affect the intensity of the reflected sound.
