Waves 3.0 / 5 based on 1 rating ? PhysicsWaves and SoundGCSEEdexcel Created by: GoCreated on: 21-12-12 17:53 What type of wave are S-waves? Transverse 1 of 19 What do four things do all waves have? All waves have a wavelength, frequency, amplitude and speed. 2 of 19 Define wavelength Wavelength is the distance from one peak to the next. 3 of 19 Define frequency and what is its unit of measurement Frequency is how many complete waves there are per second (passing a certain point). It’s measured in hertz (Hz). 4 of 19 Define amplitude. Amplitude is the height of a wave (from the mid-line to the peak). 5 of 19 What type of wave is light and all the other electromagnetic waves? Transverse 6 of 19 What type of wave are the ones on strings and springs? Transverse 7 of 19 Define speed. The speed is how fast the wave goes. 8 of 19 What type of wave is the most common Transverse 9 of 19 What type of wave are P-waves? Longitudinal 10 of 19 What type of wave is sound and ultrasound? Longitudinal 11 of 19 What are the two units of measurements that high frequencies are usually measured in, and what is it converted into Hz? kHz (1 kHz = 1000 Hz) and MHz (1 MHz = 1 000 000 Hz). 12 of 19 What type of wave are the ones that make ripples on water? Transverse 13 of 19 What type of wave is a slinky spring when you push and pull the end? Longitudinal 14 of 19 In longitudinal waves the vibrations do what? The vibrations are along the same direction as the wave is travelling. 15 of 19 Oscilloscopes always show things as what? Transverse waves - (even sound)! 16 of 19 What is the formula that links with wavelength, frequency and speed? Speed (m/s) = Frequency (Hz) × Wavelength (m) OR v = f × λ 17 of 19 What is the formula that links with wave speed, time and distance? wave speed (m/s) = distance (m) ÷ time (s) 18 of 19 A sound wave has a frequency of 19 kHz and a wavelength of 12.5 cm. Find it's speed. v = f × λ = 2375 m/s 19 of 19
