Synopsis: This is a labelled diagram showing the electromagnetic spectrum ranging from radio waves with very long wavelengths to very short-wavelength gamma radiation.There is a locator dot shown, which will be at the top left of the page when the image is the correct way up.The electromagnetic spectrum is shown as an arc like a rainbow that starts in the bottom left of the page and curves up and right to near the top centre then to the bottom right of the page.Electromagnetic waves are shown starting in the bottom centre of the page and radiating outwards and crossing the arc of the spectrum. They are labelled near the arc; the waves with long wavelength are on the left of the page and the short wavelengths on the right. Longer wavelengths have their peaks further apart and the shorter wavelengths have their peaks close together. There are two labelled arrows at the bottom centre of the page. They indicate increasing wavelength to the left and increasing energy to the right.At the top centre of the page is a smaller arc showing visible light in the middle of the spectrum. It goes from red on the left to indigo on the right.
