Question

1. For the principle quantum number n = 5, what is the greatest number of values the spin quantum number can have? a. 5 b. 25 c. 11 d. 2 e. 4

2. A grating is made with 600 slits per millimeter. What is the slit separation? a. 600 nm b. 1.67 x 10^-6m c. 3.33 x 10 ^-6 d. 160 pm e. 916 pm

3. How tall is mount everest, according to a cosmic ray muon, a subatomic particle traveling straight down toward the Earth at 0.99c? On earth, the height of Mt. Everest is viewed to be a. 1.25 km b. 176 m c. 885 m d. 6.29 km

Explanation / Answer

1) Spin quantum number canb have only 2 values i.e either +(1/2) or (-1/2)

2) spacing = 10-3/(600-1) = 1.66*10-6 m

Thus, the correct option is b. 1.67 x 10^-6m

3) Its a physics question.
