E3r light from a white source passes through a
filter that transmits only the band of wave-
lengths from 400 nm to 600 nm. when this
filtered light is incident normally on a certain
diffraction grating, the 400 nm light in one
order of the spectrum is diffracted at the same
angle, 30, as the 600 nm light in the adjacent
order. find the spacing between the lines in
the grating.

explanation: in any substance/object, the particles inside it (atoms/molecules) constantly move in random directions and with random speeds (this motion is called brownian motion). as a result, the particles have some kinetic energy (which is proportional to the temperature of the substance).

explanation:

have a great day!

work: w = fd (given)

work done by chet   =50*1 = 50 j

work done by mika =40*2 = 80 j

work done by sara =30*1.5 = 45 j

work done by bill =60*0.5 = 30 j

students in order from the greatest amount of work done to the least is mika> chet> sara> bill

hence option (b) is correct.

measure their densities same density, same sub
