Question

Question 3 0/2 points Imagining a world in which some physical constants have radically different values can often be fascinating. For example, suppose Planck's constant were (2.12x10^-9) J's (about four times the energy expended over time), and a single photon of light had enough energy to vaporize a cup of coffee (4.010x10^2) kJ). What is the maximum wavelength (in nm) of this photon?

Answer 1

* TU Now Planet's constant Value - 2.12810 9 Jos Energy of cup of coffee = 4010x10² kJ. - 9.010 X10S gule, speed of eight sle) = 3x108 m/s, the equation of enery of photo E = had fanterie - 2-1210^9 x 3808 9.010 x105 = 1.586 x 10-6 m, = 1,586 4100x109 mm 21586 mm à = he - so wave length is 1586mm - Answer [1586 mm) CScanned with CamScanner
