EM Spectrum 0.0 / 5 ? PhysicsElectromagnetic SpectrumGCSEAll boards Created by: xninaelliCreated on: 14-12-15 16:52 What can a prism do? Split 'white' sunlight into the full spectrum . 1 of 19 What is a the effect of sunlight been split into the component colours? Dispersion. 2 of 19 What is the light form being beyond red known as? Infrared. 3 of 19 What are there different types of? Electromagnet radiation. 4 of 19 What can they travel as and do ? Waves and transfer energy form one place to another, 5 of 19 What type of waves are electromagnet waves and what are they made up of ? Transverse,electric and magnetic fields. 6 of 19 What do electromagnet travel at and what else can they travel in ? The speed of light, a vacuum (space). 7 of 19 How do electromagnetic waves differ? They carry different amounts of energy. 8 of 19 Is the energy higher or lower with a shorter wavelength? Higher. 9 of 19 Is the frequency high or shorter with a shorter wavelength? Higher. 10 of 19 What come with a higher frequency? Higher energy. 11 of 19 What happens when a EM wave hits a surface? Be reflected, absorbed or transmitted. 12 of 19 What determines how waves behave? Their energy and the surface they interact with. 13 of 19 What are light waves reflected by and X-rays transmitted through Skin. 14 of 19 What usually happens to the temperature of the material when electromagnet waves absorbs it? Some of its energy is transfered into the material and the temperature rises. 15 of 19 What can some surfaces reflect? Em waves. 16 of 19 What happens to some energy reflected by EM waves? Absorbs some of their energy. 17 of 19 What does a mirror do? Reflect some of light waves that hit it. 18 of 19 What does a curved surface do? Reflects microwaves from a satellite to a receiver. 19 of 19
