Electromagnetic radiation is emitted when a neutron and proton fuse to make a deuteron. What is the wavelength of this radiation? In which region of the electromagnetic spectrum is the radiation?
wavelength = h / mv
where h = Planck's Constant = 6.626x10^-34
m = mas
v = velocity
wavelength = (6.626x10^-34 J*s)/( (3.344x10^-27 kg) (10^6 m/s)
= 1.9817x10^-13 m
That is in the Gamma Rays spectrum
The second part of the question is correct but the first part isn't. It is suppose to be in nanometers so I converted the answer you got into nm but it still isn't correct
Oh, then it would be 1.9817 x 10^-4 nm
Just a matter of conversion
I forgot to send you these tips that our professor emailed us. Maybe they'll help?
reaction: 01n + 11P --> 12d
∆m = mass
of deuteron – (mass of a proton + mass of a neutron). …it has to be in
Use: 1.67494 x 10-24 grams
for mass of o1n
Use: 31.67263 x 10-24 g for
- the mass of deuteron = 3.334370 x 10-24 g
of 11P = 1.67263 x 10-24 grams
∆E = ∆m . C2 in
Use Lambda; λ = hC/∆E where h = 6.626 x 10-34
J.s, C = speed of light = 3.0 x 108 m/s,
1 m = 109 nm.,
yes, 1.9817 x 10^-4 nm is with 4 significant figures.
That is still incorrect for some reason
hmmm... I'll recheck the numbers
That's fine. Don't worry about it. That's the same answer my friend got as well so I don't know why it's telling us that its incorrect. We'll ask our professor tomorrow. Thanks for all your help though!
Don't be sorry at all! Thank you once again!
You're welcome. Good luck :)
Thank you! :)
