Transverse wave

- Mathematics and experiments show that light is a transverse wave – the electric and magnetic field vectors point in directions that are perpendicular to the direction of motion of the light wave (and as it turns out, they also rare always perpendicular to each other).
16 hours ago · According to Sapienza, this isn't the right question to be asking. "Light is not sometimes a particle and sometimes a wave," he said. "It is always both a wave and a particle. It's just that we ...
The trough of a wave is the point on the medium that exhibits the maximum amount of negative or downward displacement from the rest position. The wave shown above can be described by a variety of properties.
Waves are characterized by several interrelated properties: wavelength (λ), the distance between successive waves; frequency (ν), the number of waves that pass a fixed point per unit time; speed (v), the rate at which the wave propagates through space; and amplitude, the magnitude of the oscillation about the mean position.
If light is a particle, then why does it refract when travelling from one medium to another? And if light is a wave, then why does it dislodge electrons ? But all behavior of light can be explained by combining the two models: light behaves like particles and light behaves like waves.
Dec 7, 2022 · Like ocean waves, light waves have crests and troughs. The distance between one crest and the next, which is the same as the distance between one trough and the next, is called the wavelength. The frequency of a wave is the number of crests (or troughs) that pass a point in one second.

For example, a plane wave is a light wave that travels through space with all of the wave crests and troughs aligned in straight lines. If we want to draw a plane wave, we can draw a line where the wave crests are, and note that they form parallel lines in space.
