Transverse And Longitudinal Waves (GCSE Physics)

A vertical displacement of a transverse wave is measured from the middle line to a crest. This quantity is called:

Which of the following is an example of a longitudinal wave?

A scientist shines unpolarised light through a polarising filter then through a second polariser rotated 90° relative to the first. What is observed?

Which property of a sound wave most directly affects its loudness as heard by a listener?

The relationship v = f × ? links wave speed v, frequency f and wavelength ?. If a wave has wavelength 2.0 m and frequency 4 Hz, its speed is:

A pulse on a string is reflected from a fixed end. The reflected pulse is:

A longitudinal wave in air has frequency 250 Hz and wavelength 1.36 m. Its speed is about:

A wave has period 0.05 s and wavelength 0.20 m. Its frequency and speed are:

In a longitudinal wave the parts of the medium that are close together are called:

Doubling the amplitude of a transverse wave (with frequency unchanged) will:

An earthquake P-wave (speed 5000 m/s) and an S-wave (speed 3000 m/s) are emitted simultaneously. If a seismometer at a distance of 200 km records the P-wave first, how much earlier (in s) does the P-wave arrive compared with the S-wave?
