I think that the answer is C)
Answer:
632 nm
Explanation:
For constructive interference, the expression is:
Where, m = 1, 2, .....
d is the distance between the slits.
The formula can be written as:
....1
The location of the bright fringe is determined by :
Where, L is the distance between the slit and the screen.
For small angle ,
So,
Formula becomes:
Using 1, we get:
For two fringes:
The formula is:
For first and second bright fringe,
Given that:
d = 0.200 mm
L = 5.00 m
Also,
1 cm = 10⁻² m
1 mm = 10⁻³ m
So,
d = 0.2×10⁻³ m
Applying in the formula,
Also,
1 m = 10⁹ nm
<u>So wavelength is 632 nm</u>
Explanation:
False.
The magnitude of average velocity is called average speed.
Acceleration is the rate of change of velocity.
