Wavelength = (speed) divided by (frequency) = 10/0.5 = 20
Wavelength = speed/frequency = 30/10 = 3 meters
In Wien's experiment it was found that when the temperature of the source increases, then the wavelength for which the radiant energy becomes maximum decreases. This displacement towards the lower wavelength side as temperature increases is termed as displacement law. So if T, the temperature of the source in kelvin and lambda m is the wavelength for which the energy is maximum. Then lambdam *T = constant. This constant is known as Wien's constant, whose value is 5.67 x 10-8 mK.
The wavelength would be12/3 x 10-15 x speed of the wave.

A wave with a wavelength of 10^-15 meters would have the greatest energy. This is because the energy of a wave is inversely proportional to its wavelength, meaning that as the wavelength decreases, the energy of the wave increases.

The energy of a photon is given by E = hc/λ, where h is Planck's constant, c is the speed of light, and λ is the wavelength of the photon. Plugging in the values, the energy of a photon with a 9 x 10^-8 m wavelength is approximately 2.21 x 10^-18 Joules.
Wavelength is 720 nanometers. Energy is 2.72 x 10-19 joules.
4.8 - 5.2 nm
The wavelength is w = hc/E = .2E-24/4E-17 = 5E-9 meters.
440 - 460 nm
The energy of a photon is given by the equation E = hc/λ, where h is Planck's constant (6.63 x 10^-34 J*s), c is the speed of light (3 x 10^8 m/s), and λ is the wavelength of the photon. Plugging in the values, we find that the energy of a photon with a wavelength of 9 x 10^-8 m is approximately 2.21 x 10^-15 Joules.
To find the wavelength of the photon, you can use the formula: wavelength = (Planck's constant) / (photon energy). Substituting the values, the wavelength is approximately 1.024 x 10^-7 meters.
The energy of a photon is given by the equation E = hc/λ, where h is Planck's constant (6.626 x 10^-34 J s), c is the speed of light (3 x 10^8 m/s), and λ is the wavelength of the photon in meters. Plugging in the values, the energy of a photon with a wavelength of 9.10^-8 m is approximately 2.18 x 10^-15 J.
