# Frequent question: What does the wavelength of electromagnetic radiation represent?

Contents

What does the wavelength of electromagnetic radiation represent? wavelength represents the lengths of the waves involved in energy transmission (length from one crest or trough to the subsequent crest of trough)The longer the wavelength, the lower the energy of the electromagnetic radiation.

## What does wavelength of radiation mean?

Definition: Wavelength can be defined as the distance between two successive crests or troughs of a wave. … The wavelength of UV radiation is shorter than violet light. Similarly, the wavelength of infra red radiation is longer than the wavelength of red light. Wavelength is inversely proportional to frequency.

Electromagnetic radiation is an electric and magnetic disturbance traveling through space at the speed of light (2.998 × 108 m/s). … Examples of EM radiation include radio waves and microwaves, as well as infrared, ultraviolet, gamma, and x-rays.

## How is the wavelength of radiation related to the energy of the photons of the radiation?

The amount of energy is directly proportional to the photon’s electromagnetic frequency and thus, equivalently, is inversely proportional to the wavelength. The higher the photon’s frequency, the higher its energy. Equivalently, the longer the photon’s wavelength, the lower its energy.

## How are wavelength and electromagnetic radiation related?

They are all related by one important equation: Any electromagnetic wave’s frequency multiplied by its wavelength equals the speed of light. We can use this relationship to figure out the wavelength or frequency of any electromagnetic wave if we have the other measurement.

## What is the wavelength of electromagnetic radiation having a frequency?

Visible light has a wavelength range from ~400 nm to ~700 nm. Violet light has a wavelength of ~400 nm, and a frequency of ~7.5*1014 Hz. Red light has a wavelength of ~700 nm, and a frequency of ~4.3*1014 Hz.

The EM spectrum.

Type of Radiation Frequency Range (Hz) Wavelength Range
radio waves < 3*1011 > 1 mm

## What happens to the wavelength and frequency of the electromagnetic waves as it progresses from left to right?

As you go from left → right, the wavelengths get smaller and the frequencies get higher. This is an inverse relationship between wave size and frequency. (As one goes up, the other goes down.)

## What is the relation between wavelength and frequency?

Frequency and wavelength are inversely proportional to each other. The wave with the greatest frequency has the shortest wavelength. Twice the frequency means one-half the wavelength. For this reason, the wavelength ratio is the inverse of the frequency ratio.

## What type of radiation has the highest wavelength?

Radio waves, infrared rays, visible light, ultraviolet rays, X-rays, and gamma rays are all types of electromagnetic radiation. Radio waves have the longest wavelength, and gamma rays have the shortest wavelength.

## What is electromagnetic radiation in simple words?

In layman’s terms electromagnetic radiation is light that travels by oscillating in waves at a constant speed carrying energy. … In layman’s terms, light travels by oscillating in waves at a constant speed carrying energy – interactions with objects vary depending on the energy these waves carry.

## How is wavelength related to energy?

Wavelength is related to energy and frequency by E = hν = hc/λ, where E = energy, h = Planck’s constant, ν = frequency, c = the speed of light, and λ = wavelength. Wavelength the distance between any given point and the same point in the next wave cycle.

## Is wavelength proportional to energy?

As frequency and wavelength have an inversely proportional relationship, the energy quantum carried is inversely proportional to wavelength.

## How is wavelength related to the energy of the colors of light?

The visible light portion of the electromagnetic spectrum shows the rainbow of colors, with violet and blue having shorter wavelengths, and therefore higher energy. At the other end of the spectrum toward red, the wavelengths are longer and have lower energy (Figure 3).

## How are the energy and wavelength of electromagnetic radiation related give relation and equation?

Just as wavelength and frequency are related to light, they are also related to energy. The shorter the wavelengths and higher the frequency corresponds with greater energy. So the longer the wavelengths and lower the frequency results in lower energy. The energy equation is E = hν.

## How do the frequency and wavelength relate of an electromagnetic wave relate to each other?

Electromagnetic waves vary in wavelength and frequency. Longer wavelength electromagnetic waves have lower frequencies, and shorter wavelength waves have higher frequencies. Higher frequency waves have more energy. The speed of a wave is a product of its wavelength and frequency.

## How are wavelength and frequency of electromagnetic radiation related with velocity?

Answer: The wavelength λ and frequency ν for any wave is related by the equation, λν=v where v is the wave velocity. For all electromagnetic waves, v=c and hence, λν=c is the relationship, where c is the speed of light in vacuum.
