![]() The amount of energy in the greenhouse rises so its temperature increases. The infrared cannot escape the greenhouse and reflects until it is re-absorbed by objects inside the greenhouse. Transmission When passing through a material, waves are usually partially absorbed The transmitted wave may have a lower amplitude because of some absorption. The plants, soil and floor emit infrared light which has a longer wavelength that is mostly reflected by glass. The plants, soil and floor in the greenhouse mostly absorb ultraviolet, and their temperature rises. Ultraviolet light has a very short wavelength, and this is mostly transmitted by the glass. Wavelength has a big effect on how much of a wave's energy is reflected, absorbed or transmitted at an interface.įor example, a greenhouse uses these differences to raise the temperature inside. ultrasound waves scanning a baby pass from flesh into bone and continue with enough energy for the machine to detect the echo.light passing through a glass window continues with over 95% of its energy.sea waves passing a shallow area continue with their energy mostly unchanged. ![]() sound waves hitting thick curtains give up their energy and the sound is muffledĬommon examples of transmission of wave energy:.sunlight landing on a face is mostly absorbed, warming the skin.waves hitting the beach usually give most of their energy to the sand.The type of wave, its properties such as wavelength, and the difference between the two media will determine what happens to most of the wave energy.Ĭommon examples of absorption of wave energy: Waves arriving at the interface (boundary) between two materials can be reflected, transmitted or absorbed. ![]()
