Answer:
∅=2021rad
Explanation:
Coherent light with wavelength 540 nm passes through narrow slits with a separation of 0.370 mm . At a distance from the slits which is large compared to their separation, what is the phase difference (in radians) i the light from the two slits at an angle of 28.0 ∘ from the centerline?
A wave is a disturbance which travels through a medium, it transfers energy without a permanent displacement of the medium itself. this is an example of light wave
using the formula below
∅=
the phase difference is given from the above
d= distance/separation of slits .00037m
=wavelength
540*10^-9m
=angle of two slits 28.0 ∘
∅=(
∅=2021rad
there are large bright fringes from the centre line
When wind turns the blades of a wind turbine and then this energy is used to power homes, this is an example of an energy transfer from mechanical to electrical energy.
<h3>What is Wind power?</h3>
- In order to produce electricity, wind turbines are mostly used in wind power or wind energy.
- In comparison to burning fossil fuels, wind energy is a well-liked, environmentally friendly, renewable energy source.
- Wind energy, like all other forms of energy production, has the potential to have negative effects on the environment, including the loss, fragmentation, or degradation of habitat for animals, fish, and plants.
- Additionally, flying animals like birds and bats could be harmed by turbine blades that are in motion.
- Wind energy is economical.
- After the production tax credit, land-based utility-scale wind is one of the least expensive energy sources on the market at 1-2 cents per kilowatt-hour.

Answer:
Sound quality
Explanation:
Loudness refers to the property of sound that depends on the amplitude of the sound wave while pitch is the property of sound that depends on the frequency of the sound wave.
Now, when sounds have the same pitch and loudness, it means they possess the same natural frequency and also, they will have similar resonance and standing waves. Despite all these similarities, the quality of these sounds will tend to vary from one to another.
