The electromagnetic spectrum includes (______) and light. The light that we see is made up of lots of different (______). Each colour has a different (______). Red light has a (______) wavelength than the other colours. Violet light has a (______) wavelength than the other colours. The longest waves in the electromagnetic spectrum are (______) waves that are used to carry signals for AM radio, (______) and FM radio. Electromagnetic waves that are a few centimetres long are called microwaves and are used to (______) (______) and transmit (______) signals over a distance. We feel the heat from sunlight, a fire, a radiator or a warm sidewalk because of (______) waves. The only part of the electromagnetic spectrum we can see is (______) light, but some (______) can see (______) waves too. X-rays have more energy than light because they have a shorter wavelength. X-rays can be sued to see the (______) in your hand. The shortest wavelength in the electromagnetic spectrum are (______) rays which are produced in radioactive atoms and in (______) explosions.
