1 (a) Which two statements about electromagnetic radiation are true?
Tick (3) two boxes.
All electromagnetic radiation is ionising.
All electromagnetic radiation travels through space at the same speed.
Only very hot bodies emit electromagnetic radiation.
Our eyes can only detect a limited range of electromagnetic frequencies.
Gamma rays are used for satellite communications.
[2]
(b) (i) Complete the table by showing the main groups of the electromagnetic spectrum from
long to short wavelengths.
Use words from the list.
Gamma rays Microwave Radio Visible X-rays Ultraviolet
Electromagnetic radiation spectrum
Long wavelength Short wavelength
Infrared
[3]
(ii) Complete the sentence about electromagnetic radiation.
Put a ring around each correct option.
When the wavelength of electromagnetic radiation gets shorter
the frequency increases / decreases / stays the same
and the energy increases / decreases / stays the same.
