As waves travel, they set up patterns of disturbance. The amplitude of a wave is its maximum disturbance from rest (its undisturbed position). Key fact It is important to note that the amplitude is ...

Researchers experimentally determined a property of cadmium called the magic wavelength which is considered essential for the development of the most accurate clocks ever envisaged. The researchers ...

Appearing as a whiteish yellow while overhead and redder when at the horizon, it's clear that the question "what color is the sun?" is actually more complex and difficult than it may initially sound.
