WebUltraviolet waves can cause skin to age prematurely and increase the risk of skin cancer. Gamma rays can also damage or kill the cells in a person's body. In order to be safe, exposure to ionising radiation needs to be kept as low as possible, especially for people who work with this type of radiation every day in hospitals. WebPoint B is still in air so is travelling faster than point A, this causes part of the wave front to refract. The whole wave front changes direction towards the normal. At the other face, point A exits the block first so the process is reversed. The wave front changes direction again so it is parallel to its original direction.

WebApr 9, 2024 · Refraction is the bending of a wave-front as it travels at different speeds over water of different depths. When different parts of the same wave-front travel at different speeds, the wave bends towards the slower part. The shallower the water, the slower the wave; therefore the wave bends towards the shallower water. WebRadio waves are transmitted easily through air. They do not cause damage if absorbed by the human body, and they can be reflected and refracted to change their direction. These properties make them ideal for communications.
