Crest (physics) A crest is the point on a wave with the maximum value or upward displacement within a cycle. E.g. All forms of wave phenomena have properties that include frequency, wavelength, and amplitude. The unit for time period is 'seconds'. The frequency describes how often particles vibration - i.e., the number of complete vibrations per second. When they reached the crest of the hill, they were able to see for miles in every direction. The wavelength can be measured as the distance from crest to crest or from trough to trough. Light is a type of electromagnetic wave. Interference is what happens when two or more waves meet each other. When the particles of the medium vibrate perpendicular to the direction of the propagation of the wave. CREST is a nationally recognised scheme for student-led project work in the STEM subjects (science, technology, engineering and maths). So we're basically multiplying by one, which is the same as doing nothing, and subtracting 273. It requires a medium for its propagation which is called sound vibration.
