Read through the full deck, or practise recalling each answer above.
Are electromagnetic waves transverse or longitudinal?
Show answer
Transverse.
What do electromagnetic waves transfer from a source to an absorber?
Show answer
Energy.
How do the speeds of different types of electromagnetic wave compare in a vacuum?
Show answer
They are all the same — every type of electromagnetic wave travels at the same velocity through a vacuum (and through air).
Electromagnetic waves form a ? spectrum.
Show answer
continuous
By which two properties are the groups of the electromagnetic spectrum ordered?
Show answer
Wavelength and frequency.
Which type of electromagnetic wave has the longest wavelength?
Show answer
Radio waves.
Which type of electromagnetic wave has the highest frequency?
Show answer
Gamma rays.
Which type of electromagnetic wave lies between radio waves and infrared in the spectrum?
Show answer
Microwaves.
Which type of electromagnetic wave lies between visible light and X-rays in the spectrum?
Show answer
Ultraviolet.
Which colour of visible light has the shortest wavelength?
Show answer
Violet (visible light runs from red at the long-wavelength end to violet at the short-wavelength end).
As wavelength decreases across the electromagnetic spectrum, what happens to frequency?
Show answer
Frequency increases — shorter wavelength means higher frequency.
Which part of the electromagnetic spectrum can human eyes detect?
Show answer
Only visible light — a limited range of the whole spectrum.
