The diagram shows water waves made by a wave machine in a swimming pool.
Every second, two waves go past a person standing in the swimming pool.
The waves have a wavelength of 0.8 metres.
Calculate the speed of the water waves.
Write down the equation you use, and then show clearly how you work out your
answer.

Q5.
The diagram below shows the range of wavelengths and frequencies for all the types
of radiation in the electromagnetic spectrum.
Page 5
X‑rays, which have frequencies in the range 1018–1021 Hz are already marked on the
diagram.
Complete the diagram by adding the following:
(a)
gamma radiation, which has shorter wavelengths than X‑rays;
(b)
radio waves which have wavelengths longer than 0.1m;
(c)
the visible spectrum which has wavelengths from 400 nm (violet) to 700 nm (red);
(d)
ultraviolet radiation (i.e. radiation with a higher frequency than violet light);
(e)
microwaves which have a shorter wavelength than radio waves and infrared
radiation which has a higher frequency than microwaves;
(f)
an FM radio programme on 92MHz. (Show this with an arrow )
