The value of Planck’s constant is 6.63×10−34Js. The velocity of light …
Solution:- As we know that, ν = c λ ⇒ λ= c ν where, λ = wavelength of a quantum of light = ? ν = frequency of a quantum of light = 8×1015s−1 c = speed of light = 3×108 m/s ∴ λ = 3×108 8×1015 =0.375 ×10−7 m = 3.75×101 nm (∵ 1m = 109nm) Hence, 4×101 will be the closest value to the wavelength (in nm) of a quantum of light with frequency 8×1015s−1.

Wavelength Calculator
Il y a 7 joursAs a default, our calculator uses a value of 299,792,458 m/s – the speed of light propagating in a vacuum. Substitute these values into the wavelength equation λ = v/f. Calculate the result. In this example, the wavelength will be equal to 29.98 m. You can also use this tool as a frequency calculator.

Wavelengths and Colors of the Visible Spectrum – ThoughtCo
By Anne Marie Helmenstine, Ph.D. Updated on April 01, 2020 The human eye sees color over wavelengths ranging roughly from 400 nanometers (violet) to 700 nanometers (red). Light from 400-700 nanometers (nm) is called visible light, or the visible spectrum because humans can see it.

Visible Light Spectrum Overview and Chart – ThoughtCo
Updated on February 14, 2020 The visible light spectrum is the section of the electromagnetic radiation spectrum that is visible to the human eye. Essentially, that equates to the colors the human eye can see. It ranges in wavelength from approximately 400 nanometers (4 x 10 -7 m, which is violet) to 700 (7 x 10 -7 m, which is red).

Il y a 7 joursThe first color is violet, corresponding to roughly a wavelength of 480 n m 480 mathrm{nm} 480 nm. We then pass blue, green, yellow, and orange till we end with red. Red light has the lowest energy (hence the greatest wavelength) that our eyes can perceive, at about 780 n m 780 mathrm{nm} 780 . We will discuss the frequency of visible …
