Waves and the em spectrum

alpha particle A type of ionising radiation emitted from a radioactive atom
amplitude the maximum distance of particles in a wave from their normal position
beta particle A type of ionising radiation emitted from a radioactive atom
cataracts when the lens in the eye becomes cloudy. Can be caused by too much UV light
electromagnetic radiation a form of energy transfer including radio, microwave, infrared, visible, ultraviolet, Xrays and Gamma rays
Fluoresence Absorbing one wavelength and re emitting the energy at another wavelength normally visible light
Frequency The number of waves passing a point per second
Gamma rays Highest frequency gamma rays
Hertz The unit for frequency 1 Hz = 1 wave per second
Infra-red radiation Electromagnetic radiation we can feel as heat
ion An atom that has been charged.
Ionising radiation UV, Xrays, Gamma radiation, alpha particle, beta partices can cause atoms to be charged.
light waves Electromagnetic radiation that can be detected by the eye.
Longitudinal Waves Waves formed by particle that vibrate backwards and forwards parallel to the direction of energy transfer
Microwaves A type of electromagnetic radiation used in mobile phone communications and heating water molecules in food.
Optic fibre Glass or plastic strand that can direct light or infra-red radiation.
radio waves Part of the electromagnetic spectrum used for communication. They have very long wavelengths and a low frequency
radioactive A material that gives out alpha, beta or gamma radiation.
radiotheraphy Cancer treatment in which a patient is given gamma radiation to kill cancer treatment.
spectrometer A device that can split up light to show the colours of the spectrum
spectrum The range of colours from red to violet obtained when white light is split up using a prism
thermal imaging Photography that uses a detector of infrared radiation
Transverse waves Waves formed by particle that vibrate at right angles to the direction of energy transfer
Ultraviolet radiation Electromagnetic radiation that has a wavelength shorter than visible light but longer than X rays
Wave speed The distance a wave travels in one second
Wavelength The distance between one crest of a wave and the next.
X rays Waves that are part of the electromagnetic spectrum. They are used for seeing inside the body.

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.
