Distance measurements based on the speed of light; used for objects in space
1 answer:
Answer : Yes, distance measurements based on the speed of light used for objects in space.
Explanation : A light year is measurement of distance that light travel in a one year.
In a one year light travels 9460000000000 kilometer.
We know that, speed of light is
and time is 31536000 seconds in 1 year
so, distance = speed of light X time
Now, the light year is
Example : The nearest star to earth is about 4.3 light year away.

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
