How can we “see” other parts of the spectrum?
- Radio waves. Giant satellite-dish antennas pick up long-wavelength, high-frequency radio waves.
- Microwaves. Because cosmic microwaves can’t get through the whole of Earth’s atmosphere, we have to study them from space.
- Visible light.
- Ultraviolet light.
- X rays.
- Gamma rays.
Which waves can you see?
Visible light waves are the only electromagnetic waves we can see. We see these waves as the colors of the rainbow. Each color has a different wavelength. Red has the longest wavelength and violet has the shortest wavelength.
How are waves used in everyday life?
Waves in Everyday Life
Sound is a type of wave that moves through matter and then vibrates our eardrums so we can hear. Light is a special kind of wave that is made up of photons. You can drop a rock into a pond and see waves form in the water. We even use waves (microwaves) to cook our food really fast.
Are gamma rays visible to the human eye?
The Visible Spectrum
Visible light is the light that we can see, and thus is the only light detectable by the human eye. Gamma rays are the most energetic light waves found on the electromagnetic spectrum. We can find Gamma rays released in nuclear reactions and particle collisions.
What three ways do we describe waves?
Radio waves, gamma-rays, visible light, and all the other parts of the electromagnetic spectrum are electromagnetic radiation. Electromagnetic radiation can be described in terms of a stream of mass-less particles, called photons, each traveling in a wave-like pattern at the speed of light.
