A student holds a ball that contains a buzzer which emits a sound at 500 Hz. The speed of sound in air is 330 m/s.
Calculate the wavelength of the sound produced.
The student throws the ball to a friend who catches the ball.
The students each hear a slightly different sound.
Explain how the sound heard by student A is different to the sound heard by student B.
The diagram below shows the sound heard by each student.
Explain which waveform each student hears and describe the differences.
This question is about water waves.
As waves pass the buoy, it oscillates.
Describe the movement of the buoy as the water passes it.
The buoy moves up and down 15 times per minute.
Calculate the time period of the waves.
Calculate the frequency of oscillation.
Describe how transverse waves differ to longitudinal waves.
A student is investigating the speed of sound in air.
The student's method is below.
- Student B measures out a distance of 100 m using a trundle wheel.
- Student A claps two wooden blocks together above their head.
- Student B is stood at the 100 m mark in direct line of sight.
- Student B starts a timer when they see the blocks touch and stops the timer when they hear the sound.
- The experiment is repeated a further 3 times.
- The students take an average of the time readings.
The students records their data in a table.
Calculate the average time for the sound to travel 100 m.
Calculate the speed of sound using the student's results.
The accepted value for the speed of sound in air is 330 m/s.
Explain why the student's value is different to this value.
Describe how the student could reduce the uncertainty in their experiment but use the same equipment.
