Electromagnetic Waves 0.0 / 5 ? PhysicsWavesGCSEAQA Created by: Emma ClareCreated on: 28-05-17 17:55 What are electromagnetic waves? They are electric and magnetic disturbances. 1 of 11 What can electromagnetic waves be used for? They can be used to transfer energy from a source to an absorber. 2 of 11 What do electromagnetic waves not transfer? They don't transfer matter. 3 of 11 What does the energy they transfer depend on? It depends on the wavelength of the wave. 4 of 11 What is the order of the electromagnetic spectrum (from smallest)? X-rays, gamma rays, ultravoilet, visible light, infared, microwaves and radio waves. 5 of 11 What speed do electromagnetic waves travel at? They travel at 3.0x10^8m/s through space in a vacuum. 6 of 11 What is the equation for wave speed? wave speed,v (m/s)= frequency,f (Hz) x wavelength,λ (m) 7 of 11 The shorter the wavelength, the higher the...? The higher the frequency. 8 of 11 What happens to the energy of waves as the frequency increases? As the frequency increases, so does the energy of the wave 9 of 11 The human eye can only detect what? The human eye can only detect visible light 10 of 11 What is the wavelength of visible light? It ranges from about 350nm to about 650nm. 11 of 11
