- 1What are transverse waves?Transverse waves have oscillations perpendicular to the direction of energy transfer. Eg.ripples on the surface of water.
- 2What are longitudinal waves?Longitudinal waves have oscillations parallel to the direction of energy transfer. Eg.sound waves.
- 3List five features in a transverse wave.Amplitude, Wavelength, Trough, Crest, Rest position.
- 4List three features in a longitudinal wave.Wavelength, Compression, Rarefaction.
- 5Increasing the amplitude...makes it LOUDER
- 6Decreasing the amplitude...makes it QUIETER
- 7Increasing the frequency and decreasing the wavelength...INCREASES the pitch
- 8Decreasing the frequency and increasing the wavelength...DECREASES the pitch
- 9Equation for wave speed using distance and time.Wave speed (m/s) = distance (m) / time (s)
- 10Equation for wave speed using frequency and wavelength.Wave speed (m/s) = frequency (Hz) x wavelength (m)
- 11Reflectedthe wave 'bounces' off
- 12Refractedthe wave passes into the new material but changes the direction in which it is travelling
- 13Transmittedthe wave passes through the material and is not absorbed or reflected
- 14Absorbedthe wave disappears as the energy it is carrying is transferred to the material.
- 15Law of reflectionThe angle of incidence equals the angle of reflection. The incidence ray and the reflected ray and the normal are all in the same plane.
- 16Refraction informationThe light bends towards the normal line when it passes through the glass because it is more dense and slows down the light. Through air the light bends away from the normal line.
