- We know from experiments that light acts as a wave. As such, it can be described as having a frequency and a wavelength. The wavelength of light is the distance between corresponding points in two adjacent light cycles, and the frequency of light is the number of cycles of light that pass a given point in one second.

Jul 27, 2023 · Relate the wavelength and frequency of light using a mathematical equation. Define electromagnetic radiation. Light is a little different from sound waves, water waves and string waves, because it can move through a vacuum. In general, the velocity of light is constant, c = 3.00 x 10 8 m/s.
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.

These different colours of light have different wavelengths and frequencies. Red light has the longest wavelength, and the lowest frequency of the visible spectrum. Violet has the shortest wavelength, and the highest frequency of the visible spectrum.
Mixing coloured materials, such as paint, is an example of subtractive colour mixing. Red paint appears red to us because when white light strikes it, the red pigments reflect the red wavelengths of light and absorball of the wavelengths. This reflected light is what is seen by our eyes. The same is true for all of the other colours. So what about ...
Light travels very fast - at the speed of light in fact!Light travels as waves.Light travels in straight lines.Light acts as a wave and can be described by a wavelength λ and a frequency ν. One property of waves is that their speed is equal to their wavelength times their frequency. That means we have: For light, however, speed is actually a universal constant when light is travelling through a vacuum (or, to a very good approximation, air).
In this section, we will focus on the wave-like properties of light. While you will later learn about wave/particle duality (how light behaves as both a wave and a particle at the same time), here we shall discuss the wave nature of light and the experimental effects of this behavior.
