WebApr 1, 2024 · An underwater transmitter uses an acoustic speaker pointed upward to the surface. The transmitter sends sound signals, which travel as pressure waves. When these waves hit the surface, they cause tiny vibrations. Above the water, a radar continuously bounces a radio signal off the water surface. WebThe UV radiations are of wavelength 10 nanometers (nm) to 400 nm, with some of it being a part of the visible light spectrum. Water absorbs more than 90% of these UV rays and hence is very good for blocking UV radiation. Alpha Radiation Alpha particles consist of protons and neutrons. They have mass and hence have less energy.
