Question

Please help me understand what this question is asking me to do

Answer 1

It says, "The product of wavelength and energy, E, is equal to the speed of light, c, multiplied by a constant, h, called Planck's constant. Use the value you obtained for the product of wavelength and energy, along with the speed of light (3.00x10^8), to calculate the value of Planck's constant h."

The value I obtained for wavelength * energy is 4.72e-26

Answer 2

Looks to me like you only posted part of the problem. Where's the rest of it?

Answer 3

@hero well I was asked to convert wavelengths and energy values before this part. I got 9.73e-8m and multiplied that by 4.8541e-19 to get 4.72e-26. If that's not enough info I can provide more.

Answer 4

"convert wavelengths and energy values". Yeah, in order to best help you, I need the original material you're getting the information from. Can't you share a page of the textbook or webpage where the original question is posted?

Answer 5

@Hero Yes, I can get that for you. It's really just instructions for the lab assignment I'm working on, but one second please

Answer 6

@Hero the link can only be accessed with a password, so I've taken screenshots of the relevant portions and post them instead

Answer 7

Sounds great.

Answer 8

@Hero In the first image, 97.3 nm and 3.03 eV are the values I used to eventually get 4.72e-26

Answer 9

What course is this?

Answer 10

@Hero Chemistry

Answer 11

That explains it. I'm not a chemistry major.

Answer 12

@Hero I figured since what I'm stuck on is mostly math involved, I could find help in Mathematics, but if you can't help, that's understandable :)

Answer 13

Yes, it's all mathematics. I think the best win-win thing for you to do would be to record all your values first and then have someone check them for you.

Answer 14

@Hero Okay, thank you for your advice and time!

Answer 15

I mean, go ahead and record the values, then screenshot them to me.

Answer 16

@Hero I converted 97.3nm to meters and got 9.73e-8. Then I converted 3.03eV to joules and got 4.8541e-19. Like I said before, I got 9.73e-8 * 3.03eV = 4.72e-26.

Answer 17

@Hero I feel confident that my values are correct, I'm just not sure how to apply them to step 5.
