Waves and Sound - SS2 Physics Past Questions and Answers - page 1
The amplitude of a wave is a measure of:
The speed of the wave
The energy carried by the wave
The distance between two consecutive crests
The time taken for one complete wave cycle
The frequency of a wave is defined as:
The distance between two consecutive troughs
The number of complete wave cycles passing a point per unit time
The time taken for one complete wave cycle
The maximum displacement of a particle from its equilibrium position
The wavelength of a wave is defined as:
The distance between two consecutive troughs
The number of complete wave cycles passing a point per unit time
The time taken for one complete wave cycle
The distance between two consecutive crests
In a wave, if the frequency increases, what happens to the wavelength?
It decreases
It increases
It remains unchanged
It depends on the medium
Which wave characteristic determines the pitch of a sound wave?
Amplitude
Frequency
Wavelength
Speed
The amplitude of a wave is doubled. What happens to the energy carried by the wave?
It doubles
It quadruples
It remains unchanged
It depends on the frequency
A wave has a frequency of 100 Hz and a wavelength of 2 metres. What is the speed of the wave?
50 m/s
100 m/s
200 m/s
500 m/s
The time period of a wave is defined as:
The distance between two consecutive crests
The number of complete wave cycles passing a point per unit time
The time taken for one complete wave cycle
The maximum displacement of a particle from its equilibrium position
The relationship between wavelength, frequency, and speed of a wave is not correct?
Wavelength = Speed / Frequency
Frequency = Speed / Wavelength
Speed = Wavelength / Frequency
Speed = Frequency x Wavelength
In a transverse wave, the particles of the medium vibrate:
In the same direction as the wave propagation
Perpendicular to the direction of wave propagation
Along the direction of wave propagation
In a random manner
