Sound is caused by the vibration of particles but not all vibrations can be heard as sound. Common ideas about sound come from the limited range of vibrations that human ears can detect.
What is the name for the distance from peak to peak of a wave?
What is the general name for waves that require a medium to vibrate?
What is the unit for time period?
What is the time period of a 40 Hz wave?
What is the frequency of a wave with a time period of 0.08 s?
How is wave speed calculated?
Wave speed = frequency ÷ wavelength
Wave speed = frequency × wavelength
Wave speed = wavelength ÷ frequency
What is the wave speed of a 1000 Hz wave with a wavelength of 0.04 m?
A boat at sea bobs up and down as waves pass. The vertical distance between a crest and a trough is 62 cm and 20 waves pass the boat in 30 seconds. What is the amplitude of the waves?
