how do i solve this ?
Answered by DrBob222
Substitute h (Planck's constant), c = speed of light, and wavelength in meters. E will be in joules.

what is h?
Answered by DrBob222
Do you have a text? notes? can you google.
h = Planck's constant = 6.626E-34 J.sec
c = speed of light = 3E8 m/s
1 m = 1E9 nm.

To be honest about it I thought that was the first constant you memorized on the first day of class. Anyway, you have it now. I'll be glad to check your work if you care to post it.
