Wavelength/Photon Chemistry Question?
Assuming you could heat up water with X-rays instead of microwaves, how manyphotons of X-ray radiation with wavelength (A) of 5.61 x 1 o-9 m will be needed to causethe same amount of heat increase as 1. 7 4 x 1028 of photons of microwave radiation withwavelength of 0.112 m?

E = h*nu = hc/lambda.
That is to say, energy varies inversely with wavelength. Therefore,
( X )/5.61 * 10^(-9) m = (1.74 x 10^28)/(0.112 m), so
X = about 8.7 x 10^20 (number of Xray photons)
