What is the formula for the energy of a wave?

m = μΔx
The Energy of a Wave Formula Δ m = μΔx. The total mechanical energy of the wave is the sum of its kinetic energy and potential energy.

What is the energy of photons that corresponds to a wave number of 5 10 − 5m − 1?

The energy corresponding to this line will be. =9.93×10-23kJ.

How do you find the energy of a wave number?

The energy associated with a single photon is given by E = h ν , where E is the energy (SI units of J), h is Planck’s constant (h = 6.626 x 10–34 J s), and ν is the frequency of the radiation (SI units of s–1 or Hertz, Hz) (see figure below).

What is the energy of photon that corresponds to a wave number of 6/10 − 5 cm − 1?

Hence, the energy of photons is 5.1×10−21erg 5.1 × 10 − 21 e r g .

How do you calculate energy in Joules?

In equation form: work (joules) = force (newtons) x distance (meters), where a joule is the unit of work, as defined in the following paragraph. In practical terms, even a small force can do a lot of work if it is exerted over a long distance.

How do you find energy in Joules from wavelength?

The equation for determining the energy of a photon of electromagnetic radiation is E=hν , where E is energy in Joules, h is Planck’s constant, 6.626×10−34J⋅s , and ν (pronounced “noo”) is the frequency. You have been given the wavelength λ (pronounced lambda) in nanometers, but not the frequency.

What is the energy of photon that corresponds?

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.

What is the energy of photon that corresponds to a wave number of 5?

5×10−20erg.

What is the energy in Joules?

1 Joule (J) is the MKS unit of energy, equal to the force of one Newton acting through one meter. 1 Watt is the power from a current of 1 Ampere flowing through 1 Volt. 1 kilowatt is a thousand Watts. 1 kilowatt-hour is the energy of one kilowatt power flowing for one hour.

How do you find energy in Joules?

Multiply watts by seconds to get joules. A 1 Watt device consumes 1 Joule of energy every 1 second. If you multiply the number of watts by the number of seconds, you’ll end up with joules. To find out how much energy a 60W light bulb consumes in 120 seconds, simply multiply (60 watts) x (120 seconds) = 7200 Joules.

How many wavenumbers are there in the unit of energy?

Wavenumber is a non-standard unit, but it has its own pedantic semantics. You will be perfectly understood if you say that the energy is 15800 wavenumbers, but the pedanticists would have you say that the energy corresponds with a wavenumber of 15800.

What is the bandwidth of 10 cm -1 using wavenumber?

So a bandwidth of 10 cm -1 would be a bandwidth of 1.24 meV. Wavenumber is a non-standard unit, but it has its own pedantic semantics. You will be perfectly understood if you say that the energy is 15800 wavenumbers, but the pedanticists would have you say that the energy corresponds with a wavenumber of 15800.

What is the energy of photons that corresponds to wave number?

What is the energy of photons that corresponds to a wave number of 2.5 × 10^-5cm^-1? What is the energy of photons that corresponds to a wave number of 2.5 ×10−5cm−1? We know that wave number is reciprocal of the wavelength. Hence, the energy of photons is 5.0×10−21erg.

What is the wavelength of light with a wavelength of 4000 nm?

Wavelength in nm = 10,000,000/ cm-1 so the wavelength of light having a wavenumber of 4000 cm-1 => 2500 nm 10,000,000/4000 = 2500 nm How to convert microns or nm to cm -1 (inverse cm)
