Describe an electromagnetic wave
They are used to transmit energy.
1 of 7
Explain the difference between transverse and longitudinal waves and give some examples
Transverse waves are perpendicular to the direction of the wave. Eg. visible light. In longitude waves the vibrations are along the direction of the wave.
2 of 7
Label a diagram of a wave with: wavelength, amplitude, trough and crest/peak
Wavelength: the distance between 2 waves. Amplitude: the distance between the middle ft the wave to the top. Trough: the bottom of the wave. Crest: the top of the wave.
3 of 7
List the different waves in the electromagnetic spectrum
Radio, microwave, infrared, visible light, ultraviolet light, x-ray and gamma ray.
4 of 7
Give uses of the waves in the electromagnetic spectrum
Radio: transmits TV Microwaves: can be used for cooking. Infrared: can be used to sense heat. Visible light: make us see. Ultraviolet light: to sterilise things. X-rays: to look inside your body. Gamma rays: are used to treat internal organs
5 of 7
Give dangers of the waves in the electromagnetic spectrum
Radio: can cause cancer. Microwaves: internal heating of body tissues. Infrared: internal heating of body tissues. Visible light: Ultraviolet light: can affect eyes and skin X-rays: can lead to cancer. Gamma rays: can lead to cancer.
6 of 7
Explain the importance of electromagnetic waves in medicine
Ultraviolet light: is used to sterilize things. X-rays: show inside the body to see if there is any damage. Gamma rays: are used to kill cells. These all help to heal us and make sure we don’t get further damage.
