How do infrared radiation used in television remotes?
Infrared is a invisible kind of red light that objects give off. There is a little led light that the beam comes out of, It sends out a beam of infrared waves, by sending different codes for different commands at the speed of light that you wanted your TV to do, a micro chip inside a tv collects the beam and finalizes the commands although you press a command on the remote, you cannot not see an infrared light.
Explain what the purpose is of radiation therapy as a treatment for cancer, and identify what type of wave from the electromagnetic spectrum is used in the therapy.
the purpose of radiation therapy is that, it uses a concentrated radiation beam that will kill cancer cells although this is a benefit there comes some risks, there risks includes hair loss, earaches, mouth sores, nausea, swelling, vomiting and many more that are just as bad.The types of waves that are used in this therapy are x-rays and Gamma Rays
Using the principle of refraction, explain why a swimmers leg looks different underwater compared to out of the water.
The main reason why legs look different under water is because the change of the speed of light. It changes as it passes from the one substance to another, this usually results to the change of direction, the light is bending when is is traveling to the eye this is why the image you see under water could because different to what is really is
How was the bionic eye developed? Include information on how it works, what is macular degeneration, and which patients does it benefit?
A bionic eye is developed by using a variety of electrodes. It is placed onto the retina that is in the eye and is uses to give signals that come from the camera, the camera works by it converting a light. it then uses electrical signals that show the brightness of the light, using these signals it makes an image on the back of the camera. the benefits of the bionic eye is it helps people with little vision or and no vision, Macular Degeneration An eye disease that slowly destroys the macula which damages the central vision.
