can anyone help??

oh thanks a lot, i used the equation to get frequency and for the wavelength, i used E = (h)(c) / λdoes it look right?

Homework Statement Calculate the frequency and wavelength of a photon with 6.2 x 10^4 eV of energy. I have no idea where to start, so can anyone please point me in the right direction.

Homework Statement A diffraction grating uses light with a wavelength of 475 nm to generate an interference pattern. if the highest order maximum that appears is the fifth-order. what is the density of the grating in lines/cm? Homework Equations sinθ = mλ / d t= (m + 1/2) (λ) / 2...

thanks a lot, i got the idea and concept

hi, i have a question that i don't really get, so anyone to help? Explain, using the domain theory , why heating or dropping a magnet can cause it to lose its magnetization? thanks to anyone who would help
