   Jun 29, 2020 · 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.

   Light is a transverse, electromagnetic wave that can be seen by the typical human. The wave nature of light was first illustrated through experiments on diffraction and interference. Like all electromagnetic waves, light can travel through a vacuum. The transverse nature of light can be demonstrated through polarization.

   How do you describe light with its frequency and wavelength?

   • Describe light with its frequency and wavelength. Describe light as a particle of energy. What is known as light is more properly called electromagnetic radiation. We know from experiments that light acts as a wave. As such, it can be described as having a frequency and a wavelength.

   Is light a wave or a particle?

   • Neither: light is its own unique phenomenon – the outcome of an interaction between electrical and magnetic fields – and it behaves like both waves and particles. Most of us were taught at school that light is a wave. This is because it does things that waves do. So, for example, waves undergo interference.

   Is light a wave?

   • This difficulty gets greatly magnified for the case of light. 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.

   Is light a wave or a molecule?

   • 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 traveling through a vacuum (or, to a very good approximation, air).

   How are wavelength and frequency related?

   • Wavelength (λ) and frequency (f) are related because all electromagnetic waves travel at the same speed. To see how this works, imagine a parade in which everyone is forced by prevailing traffic conditions to move at exactly the same speed. You stand on a corner and watch the waves of marchers come by.

   Is the wavelength of a light wave inversely proportional to its frequency?

   • The wavelength of a light wave is inversely proportional to its frequency. Light is often described by it's wavelength in a vacuum. Light ranges in wavelength from 400 nm on the violet end to 700 nm on the red end of the visible spectrum. Phase differences between light waves can produce visible interference effects.
