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

Physics
1 answer:
Artyom0805 [142]3 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.

Tatiana [17]

Translating the first sentence into equation we get, t = k(1/h) where t is time in seconds, k is the constant and h is the horsepower. Substituting the values in the equation we have, 12s = k(1/200) we have a k = 2400 seconds – hp. To get the time at 240 hp we use the equation above and the constant, we get, t = (2400 seconds-hp)(1/240hp) t = 10seconds.

White light is incident on a diffraction grating. What color is the central maximum of the interference pattern?
lara [203]

Answer:

The color of the central maximum is white.

Explanation:

A diffraction grating in optics is generally known as an optical component that contains a periodic structure. It is commonly used to breakdown and diffract light into different beams that move in several directions. For example, if a light ray is allowed to pass through the component (i.e. diffraction grating), the   central maximum will have a white color.

A guitar string produces 3 beats/s when sounded with a 352-hz tuning fork and 8 beats/s when sounded with a 357-hz tuning fork.
MA_775_DIABLO [31]

Explanation:

The fluctuating sound heard when two objects vibrate with different frequencies is called beats. It is given that guitar string produces 3 beats/s when sounded with a 352 Hz tuning fork and 8 beats/s when sounded with a 357 Hz tuning fork.

It is assumed to find the vibrational frequency of the string.

For 3 beats/s, beat frequency can be :

352 - 3 or 352 + 3 = 349 Hz or 355 Hz

For 8 beats/s, beat frequency can be :

357 - 8 or 357 + 8 = 349 Hz or 365 Hz

It means that the vibrational frequency is 349 Hz.
