Answer:
To protect us.
Explanation:
For ex. your dunking on a basketball hoop if that wasn't strong you would fall on your back and get injured.
The paths of the light waves that interfere cause first-order lines to differ in length by the wavelength of the light.
The phenomenon of wave interference occurs when two waves meet while traveling in the same medium.
As the two light waves interfere in the first order they interfere by differing the consecutive lengths by the wavelength of the light. The wavelength of the light can be defined as the distance between identical points (adjacent crests) in the adjacent cycles of a wave signal propagated in space or along a wire.
Hence, it can be concluded that the paths of the light waves that interfere cause first-order lines to differ in length by the wavelength of the light.

Answer:
4.38 m/s^2
Explanation:
If,
Initial velocity(u) is 9.2 m/s
Final velocity (v) is 19.1 m/s
Distance moved(s) in that period is 32 m
Therefore we use the formula,
v^2 = u^2 + 2as
; (19.1)^2 = (9.2)^2 + 2(32)a...then move the variables without a to one side..,
; 280.17 = 64a...then divide both sides by 64
; Acceleration = 4.38 m/s^2
Answer:
B is a false statement
Explanation:
Because the law of energy conservation state that energy can neither be created nor destroyed
