You need to know about these quantities used in waves - what they mean, the symbols used for them and the units used to measure them. The amplitude (\(a\)) of a wave is the distance from the ...

For instance, when light travels from air to glass or water waves travel from deep to shallow water. FAST is a useful way of remembering the speed and direction changes of waves during refraction ...

The film "Simple Waves" demonstrates the properties of waves and pulses using various mediums like springs and rubber tubes. It explores how wave speed depends on the medium and its conditions, ...

As an airplane flies faster than the speed of sound, it "pushes" on the sound waves in front of it. But sound waves obey the speed limit—they can't travel faster than the speed of sound.

Setting a wave speed record is only part of the result; using the same waves to monitor the plastron's stability is another. Maintaining the delicate gas layer on top of the superhydrophobic ...

The propagation is mathematically modelled by the wave equation which gives a connection between the wave speed (a property of the medium) and the sound wave (oscillation in the medium). If we are ...
