Distance of wall from CD 
Second bright fringe 
Let
Strontium vapor laser has a wavelength \lambda= 431 nm=>431 *10^{-9}m
Generally the equation for Interference is mathematically given by
Where
Answer:
B
Explanation:
the battery isn't chemical energy so any answer saying that you can cross out and that leaves you with B
A small, rocky particle that moves through space and strikes a planet or moon is referred to as a meteorite. A meteorite is a substantial part of the wreckage from a root such as an asteroid including comet, It is described as a meteoroid before its collision. Meteorite's intensity can change from petite to remarkably big.
Answer:
True
Explanation:
You can describe the
motion of an object by its
position, speed, direction,
and acceleration.
The resistance of wire B will be D. 1/2R
<h3>What is resistance?</h3>
It should be noted that resistance simply means the measure of the opposition to the current flow that's in an electric circuit.
Based on the information given, the resistance will be calculated thus:
= 2L/4A
= 1/2pL/A
= R/2
Therefore, the resistance of wire B will be D. 1/2R
