Yr 10 Physics Intervention Pack: Waves and Electromagnetic Waves Q1 perpendicular energy flow Waves transfer energy from one place to another. Waves may be mechanical (when matter oscillates eg water waves) or electromagnetic (eg visible light, radio waves). Waves may transverse or longitudinal. In a transverse wave the oscillations are ………………………………………………. to the energy flow. In a longitudinal wave the oscillations are parallel to the …………………………………………….. . Q2 wavelength second maximum The amplitude of a wave is the ……………………………………………………… displacement of a point on a wave from the undisturbed position. The ………………………………………………………..of a wave is the distance from a point on one wave to the equivalent point on the adjacent wave. The frequency is the number of waves passing a point each……………………………………………… . Q3 velocity transverse Electromagnetic waves are ……………………………………………… waves that form a continuous spectrum. All electromagnetic waves travel at the same …………………….through a vacuum (space) or air.
