Answer:
0.48 cm
Explanation:
given data
wavelength = 480 nm
wavelength = 560 nm
slit spacing = 0.040 mm
distance between double slits and the screen = 1.2 m
solution
we know that (1 nm= m)
we wil take here equation of equations of interference that is
ym = R × (m λ)/d ..........................1
here m = 2 R i.e distance of screen and slit
so put here value and we get
separation between the second-order bright fringes = 0.48 cm
Answer:
Option A
Explanation:
Your answer is the first option or "C/kg." C/kg is a ratio for specific charge. C for the charge of the electron, kg for the mass of the electron. To find the specific charge we divide the two, which usually involves scientific notations and simplifying.
