Using E = hc/λ (Example 1)

In this video, we calculate the energy associated with a photon of a given wavelength.

The units of Planks constant*speed of light is J.M.

[@anoushkazarians]

Normally, yes! The units we get after multiplying Planck's constant by the speed of light would be J · m if that's all we were doing, but since we have a length in the denominator, its unit of meters (m) cancels with the meters (m) in the numerator, leaving behind only the Joules (J) as our sole unit for the calculation shown here.
