Physics: waves
Flashcards do conjunto (12)
- 1What do Waves do?They transfer energy from place to place without matter (solid, liquid, gas)
- 2What types of waves do not need to travel through a substance?Visible light, infrared rays, microwaves and other types of electromagnetic radiation
- 3What is the amplitude of a wave?Its maximum disturbance from its undisturbed position, NOT the distance between the top and bottom of a wave
- 4What is the wavelength and how can you measure it?The distance between a point on one wave and the same point on the next wave. It is often measured from the peak to the trough.
- 5What is the frequency of a wave?The number of waves produced by a source or pass a certain point each second.
- 6What is the unit for frequency?hertz (Hz)
- 7What is the period of a wave?The period of a wave is the time taken for one wave to be produced
- 8What is the wavefront?The imaginary surface we draw to represent the vibrating part of a wave
- 9What is a Transverse wave?
- 10What is a longitudinal wave?
- 11What are Osillations or vibrations parallel to in a longitudinal wave?the direction of energy transfer
- 12Describe Refractionwhen waves move between mediums (materials) they can change speed, wavelength and direction
