What is meant by the statement that a laser beam is coherent, mono-chromatic and parallel?

Physics
1 answer:
Artyom0805 [142]4 years ago
8 0

Answer:

Laser light however contains only one wavelength. This property makes lasers monochromatic, meaning of one color. Another property of lasers is that all the wavelengths are in phase, meaning they wave together. This property is called coherency. Laser light travels in the same direction, parallel to one another.

A woman is standing in the ocean, and she notices that after a wave crest passes by, five more crests pass in a time of 50.2 s.
lorasvet [3.4K]

Explanation:

(a) The period of a wave is the time required for one complete cycle. In this case, we have the time of five cycles. So:

T=\frac{t}{n}\\\\T=\frac{50.2s}{5}\\T=10.04s

(b) The frequency of a wave is inversely proportional to its period:

f=\frac{1}{T}\\f=\frac{1}{10.04s}\\f=0.01Hz

(c) The wavelength is the distance between two successive crests, so:

\lambda=30.2m

(d) The speed of a wave is defined as:

v=f\lambda\\v=(0.1Hz)(30.2m)\\v=3.02\frac{m}{s}

A horse gallops for 3.5 minutes around the raceing track. During this time it changes velocity from 543 min to 628 min. Calculat
enot [183]

Answer:

The acceleration of the horse during this time interval is 24.286 m/min²

Explanation:

Given;

initial velocity of the horse during the gallop, u = 543 m /min

final velocity of the horse during the gallop, v = 628 m /min

time of motion, t = 3.5 minutes

The acceleration of the horse is given by the change in velocity per change in time;

a = \frac{v-u}{t}\\\\a = \frac{628-543}{3.5}\\\\a = 24.286 \ m/min^2

Therefore, the acceleration of the horse during this time interval is 24.286 m/min²

Far from any other masses, two masses, m1 and m2, are interacting gravitationally. The value for the mass of m1 suddenly doubles
NNADVOKAT [17]
<span>It also doubles The gravitational force between two masses is expressed as: F = G*m1*m2/r^2 where F = Force between the two masses m1 = Mass of object 1 m2 = Mass of object 2 r = distance between centers of object 1 and object 2 G = Gravitational constant The exact values of G, m1, m2, and r don't matter since all except for m1 is held constant. And when m1 suddenly doubles, the force attracting the two object to each other also doubles.</span>
