What is the energy per photon of a light source if it has a wavelength of 460 nm?
E = h*c/(wavelength)
h is Planck's constant and c is the speed of light. Find their values and do the calculation.
To calculate the energy per photon of a light source, you can use the equation:
E = hc / λ
Where:
- E represents the energy per photon,
- h is Planck's constant (approximately 6.626 x 10^-34 J·s),
- c is the speed of light (approximately 3.00 x 10^8 m/s),
- λ is the wavelength of the light source.
To solve this question, we can plug in the values:
λ = 460 nm = 460 x 10^-9 m (converting from nanometers to meters)
E = (6.626 x 10^-34 J·s * 3.00 x 10^8 m/s) / (460 x 10^-9 m)
By performing the calculation, we can find the energy per photon of the light source with a wavelength of 460 nm.
