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?

Oct 20th, 2017

wavelength = h / mv

where h = Planck's Constant = 6.626x10^-34

m = mas

v = velocity

therefore,

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

Apr 27th, 2015

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?

- The reaction: 01n + 11P -->  12d

∆m = mass of deuteron (mass of a proton + mass of a neutron). …it has to be in kg

- Use:  1.67494 x 10-24 grams for mass of  o1n

- Use:  31.67263 x 10-24 g for mass of

-  the mass of deuteron = 3.334370 x 10-24 g

mass of 11P = 1.67263 x 10-24 grams

Calculate ∆E = ∆m . C2  in J

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.,

give 4 significant figures

Apr 27th, 2015

yes, 1.9817 x 10^-4 nm is with 4 significant figures.

Apr 27th, 2015

That is still incorrect for some reason

Apr 27th, 2015

hmmm... I'll recheck the numbers

Apr 27th, 2015

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!

Apr 27th, 2015

ok, sorry.

Apr 27th, 2015

Don't be sorry at all! Thank you once again!

Apr 27th, 2015

You're welcome. Good luck :)

Apr 27th, 2015

Thank you! :)
