Suppose you are observing the interference pattern formed by a Michelson interferometer in a laboratory and a joking colleague h

olds a lit match in the light path of one arm of the interferometer. Will this have an effect on the interference pattern
Physics

Troyanec [42]4 years ago
7 0

Answer:

Explanation:

In Michelson interferometer , two light waves from different directions are made to overlap so that fringes are formed on the screen due to interference . In it,  two monochromatic and coherent light are made to overlap which have some path difference or phase difference. They form dark and bright fringes .

Now when a match stick is lit in the path of a wave , the fringes will disappear  and an general illumination will be observed on the screen as the light from the lit match stick will not be coherent . Incoherent light can not form stable fringes.

Consider the concepts of kinetic energy (KE) and gravitational potential energy (GPE) as you complete these questions. A ball is
Lena [83]

Answer:

When the ball is held motionless above the floor, the ball possesses only GPE  energy.If the ball is dropped, its GPE energy decreases as it falls.If the ball is dropped, its KE energy increases as it falls.

Explanation:

If the ball is held motionless, then its kinetic energy is equal to zero, since kinetic energy depends on the velocity. And the ball is held above the ground, which means it possesses gravitational potential energy.

If the ball is dropped, its height will decrease, therefore its gravitational potential energy will decrease. Along the way, the ball will be in free fall, and therefore its velocity will increase, hence its kinetic energy.

You want to place a mirror at a blind turn on the staircase in your house. Which would be best suited for this purpose?
Eduardwww [97]
You can't see beyond a blind turn, so a mirror would allow you to see around the corner.

An electric field of 260000 N/C points due west at a certain spot. What is the magnitude of the force that acts on a charge of -
olga55 [171]

Answer:

Electric force on the charge will be equal to -1742000 N

Explanation:

We have given electric field at a point is E = 260000 N/C

And charge q = -6.7 C

We have to find the force on that charge

Force on the charge is equal to Force = charge × electric field ( multiplication of electric field and charge )

So force will be equal to F=260000\times -6.7=-1742000N

So electric force on the charge will be equal to -1742000 N
