I'm pretty sure it's 20m/s because 1300m divided by 65 seconds is 20 so I think it's 20m/s
Explanation:
Yes, it do, for a short time.
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
