# What is the energy of a wavelength of light at 450 nm?

The energy of a wavelength of light at 450nm is equal to the Planck Constant of 6. 626 x 10^-34 multiplied by the speed of light (2. 998 x 10^8 m/s) divided by 450 x 10^-9m, which comes to 3. 34 x 10^-19 Joules.

This is the amount of energy that exists in a single photon of light with a wavelength of 450 nm.

## What is the energy of 480 nm wave?

The energy of a 480 nm wave can be determined through the knowledge that energy and frequency are linked, with E (energy) = h (Planck’s constant) x f (frequency). This can then be used to calculate the energy of a particular wavelength.

As the frequency of a 480 nm wave is 6. 25×1014 Hz, then the energy of the wave can be calculated by multiplying this frequency by Planck’s constant, which is 6. 62607004 x 10-34 J/s. This would give a total energy of 4.

182 x 10-19 J.

## What color is 450 nm in wavelength?

450 nm in wavelength corresponds to a color in the blue-violet range of the visible spectrum. Light at this wavelength is not actually seen as a distinct color by the human eye, but rather as a combination of blue and violet hues.

For example, a light at 450 nm may appear to be a light purple or lavender.

## How do you calculate energy from wavelength?

Energy can be calculated from wavelength by using the equation E=hc/λ, where E is the energy injoules, h is Planck’s constant (6. 626×10^-34 J*s), c is the speed of light (2. 998×10^8 m/s) and λ is the wavelength in meters.

To calculate the energy in terms of frequency, use E=hf, where h is Planck’s constant and f is the frequency in Hertz. For example, a light wave with a wavelength of 500 nm (0. 5×10^-6 m) would have an energy of 4.

12×10-19 J, while a wave with a frequency of 683 THz (683×10^12 Hz) would have an energy of 4. 44×10-17 J.

## How much energy is in 1 mole of 400 nm wavelength?

At 400 nm wavelength, 1 mole of photons (photon energy) has a total energy of 1. 88 x 10^-18 Joules. This energy is calculated using Planck’s Constant (h) and the wavelength of the photon (λ): Energy = hc/λ, in which c is the speed of light.

The Planck constant is equal to 6. 626 x 10^-34 J·s, and the speed of light is equal to 3 x 10^8 m/s. So, 1 mole of photons at 400 nm has a total energy of 1. 88 x 10^-18 Joules.
