Light is called an 'electromagnetic wave' for historical reasons* in the following sense: It turned out that the effects of visible light and other radiation can be calculated using Maxwell's equations, which are also used to model the behaviour of electrically charged particles. This was an instant of a successful unification and it hasn't ...
May 24, 2024 · We know that light is a wave based on how it behaves – it exhibits the same properties of other waves we have examined – it interferes with itself, it follows an inverse-square law for intensity (brightness), and so on.
Sound waves are energy waves that compress matter - you can't have a sound wave in a vacuum. Light waves are energy waves too, but they don't need matter to go forward. That's why we can see sunlight, but we can't hear the sun.
Nov 21, 2024 · Rather than absorbing light continuously from a wave, atoms actually receive energy in packets of light called photons, explaining odd observations such as the existence of a cutoff...
Apr 28, 2014 · Isn't this technically inaccurate, because light consists of quanta of electromagnetic radiation called photons? Because photons are discrete particles, they have a certain amount of energy, but not a wavelength because they are not waves.
Light is a type of electromagnetic radiation that can be detected by the eye. It travels as a transverse wave. Unlike a sound waves, light waves do not need a medium to pass through,...
