The Electromagnetic spectrum 0.0 / 5 ? PhysicsElectromagnetic SpectrumGCSEAQA Created by: Mr_MackintoastCreated on: 29-03-17 17:30 What are electromagnetic radiations? Electromagnetic radiations are electric and magnetic disturbances. They travel as waves and move energy from place to place. 1 of 8 Do electromagnetic waves travel through a vacuum? All electromagnetic waves travel through a vacuum (e.g. space) at the same speed 2 of 8 What is the electromagnetic spectrum? All of the waves together are called the electromagnetic spectrum. 3 of 8 What makes up the electromagneitc spectrum (in order of increasing wavelength) Spectrum: Gamma Rays, X-Rays, Ultraviolet, Visible, Infrared, Microwaves, Radio Waves 4 of 8 Does the electromagnetic spectrum stop? The electromagnetic spectrum is continuous. 5 of 8 How are different wavelengths reflected, absorbed or transmitted? Different Wavelengths of the electromagnetic spectrum are reflected, absorbed or transmitted differently by different substances and types of surface 6 of 8 The [what] the frequency of an electromagnetic wave, the more energy it transfers? The higher the frequency of an electromagnetic wave, the more energy it transfers 7 of 8 What is the wave speed that electromagnetic waves travel through a vacuum at? All electromagnetic waves travel through space at a wave speed of 300 million m/s 8 of 8
