Which statement is true about destructive interference of light

Physics
1 answer:
adoni [48]3 years ago
6 0

Answer:

A pair of light or sound waves will experience interference when they pass through each other. Destructive interference occurs when the maximal of 2 waves are 180 degrees out of phrase: A positive displacement of one wave is canceled exactly by a negative displacement of the other wave.

If a 25 kg object is moving at a velocity of 10 m/s, the object has<br> energy. Calculate it.
Paul [167]

Answer: Your answer is 1250J

Explanation:

K E = 1/2 m v 2

The mass is  

m = 25 k g

The velocity is  v = 10 m s − 1

So,

K E = 1 /2 x25 x 10 2^2= 1250 J

a coil of 40 henry inductance is connected in series with aresistance of 8ohm and the combination is joined to the terminals of
Andreyy89

Answer: 5 seconds

Explanation:

Given the following :

Inductance (L) = 40 henry

Resistance = 8 ohms

The circuit given above is a Resistor - Inductor (RL) circuit network. The time constant of an RL circuit is the ratio of the circuit Inductance (L) and Resistance (R). Time constant is measured in seconds.

THAT IS;

Time constant = L / R

THEREFORE ;

Time constant = 40 / 8

Time constant = 5 seconds
