1.	37. The energy of a photon is 3x10-12 ergs. Whatis its wavelength in nm ?(h=6.62 x 10-27 erg. sec; C=3x1010Cm.s-1)
Answer» Using Planck's formula,E=hc/wwhere w is the wavelength,310^(-12) = 6.6210^(-27) * 310^10 / ww = 6.6210^(-5) cm = 662 nm. Hope it helps.Mark as best if I am correct. 662nm is the right answer by E=HC/W622nm answer 622nm is the correct answer of this problem 622nm is the correct answer

Answer»

Using Planck's formula,E=hc/wwhere w is the wavelength,3*10^(-12) = 6.62*10^(-27) * 3*10^10 / ww = 6.62*10^(-5) cm = 662 nm.

Hope it helps.Mark as best if I am correct.

662nm is the right answer

by E=HC/W622nm answer

622nm is the correct answer of this problem

622nm is the correct answer
