(C)
visual estimation of height of the beanbag
(E)position of the fulcrum for the lever affecting transfer of energy
Answer:
820 nm
Explanation:
We are given that
Wavelength=



For first minimum therefore
m=0
We know that for destructive interference

Substitute the values



Hence, the distance between two slits that produces the first minimum=820 nm
