h is Planck’s constant. Provided on your exam data sheet (6.626×10-34 J.s) This equation is said to define the relationship between energy and frequency in a black body. What is H in eV? planck constant value.

What is H value in e HV?

E = hv C= λv. E is the energy of the light in Joules (J), h is a constant which is 6.626 X 10-34 J·s, and. v is the frequency of the light in s-1 or waves/s (also called Hertz (Hz). C is the speed of light.

What is the H in HV?

where h is Planck’s constant, c is the velocity of light, ν is frequency, and λ is wavelength.
