487 Joules corresponds to 487 nm.
Visible light ranges from approximately 380 to 750 nanometers (nm) in wavelength. In terms of frequency, this corresponds to a range of about 790 terahertz (THz) to 400 THz. When expressed in joules, the energy of visible light photons ranges from about 3.24 x 10⁻¹⁹ joules (for red light at 750 nm) to about 5.24 x 10⁻¹⁹ joules (for violet light at 380 nm).
The energy of this photon is 3,7351.10e-19 joules.
3.96 10-19 j
3.84 x 10-19 joules.
Newton x meter is joules. (Please note that Nm is also used for torque; in this case, it happens to have the same units, but it is unrelated to energy, and can therefore not be converted to energy units.)
The energy is 18,263.10e4 joules.
Each photon has an energy of 4.9*10^-19 J.
Answer #1: Joules (J) or Newton metres (Nm)==================================Answer #2: Energy
The element that emits a spectral line at 768 nm is hydrogen. The 768 nm spectral line corresponds to the transition of an electron from the 5th energy level to the 2nd energy level in a hydrogen atom.
Joules or Newton-meters.1 J = 1 Nm
The energy of a violet photon with a typical wavelength of around 400 nm is approximately 3.1 x 10^-19 joules.
The energy of red light with a wavelength of 700 nm can be calculated using the formula E = hc/λ, where E is the energy, h is Planck's constant, c is the speed of light, and λ is the wavelength. Plugging in the values, you can calculate the energy in joules.
