Q1-

The smallest mass one of our analytical balances in the quant lab can weigh is 0.0001 g.  How many photons of 560 nm light would it take to have a mass of 1.000 x 10-4 g.

h = 6.626 x 10-34 J·sec.                                                                                 

c = 3.00 x 108 m/sec.  

 

 

 

Q2-

What is the wavelength of neutrons traveling at 9.23 x 106 m/sec?             

h = 6.626 x 10-34 Jsec.                                                                        

c = 3.00 x 108 m/sec.                                                                          

mneutron = 1.67 x 10-27 Kg
