Question

Given the following information, what is the approximate frequency of this photon?


(E) energy =5 x 10^-24


Jh = 6.6 x 10^-34 J/s

3 x 10^-58 Hz

8 x 10^9 Hz

1 x 10^-10 hz

3 x 10^-37Hz
@Ac3

Answer 1

are those the options?

Answer 2

yes

Answer 3

this falls to simple dimensional analysis Hz=1/second

Answer 4

so just grab your Jh and divide by the energy which will give you 1/second units which is hertz and then you pick the nearest one.

Answer 5

it looks like it'll be the 3rd one.

Answer 6

how would you do that

Answer 7

dimensional analysis.

Answer 8

6/5=1.something and you have -34 exponent on top and -24 on bottom. Without calculator I know the answer will be 1.something*10^-34

Answer 9

my bad 1.something*10^-10

Answer 10

is what i meant

Answer 11

ok so it would be c

Answer 12

that's the closest one to the answer you get so yes.

Answer 13

Ok thank You
