To solve this problem we will apply the concepts given by the principles of superposition, specifically those described by Bragg's law in constructive interference.
Mathematically this relationship is given as
Where,
d = Distance between slits
= Wavelength
n = Any integer which represent the number of repetition of the spectrum
Calculating the value for n, we have
n = 1
n=2
n =3
Therefore the intensity of light be maximum for angles 23.3° and 52.28°
Answer:
eardrum is the correct answer
hope this helps ❤️
Explanation:
Sound waves enter the ear canal and cause the eardrum to vibrate. Three small bones transmit these vibrations to the cochlea. This produces electrical signals which pass through the auditory nerve to the brain, where they are interpreted as sound.
Answer:
1.37 rad/s
Explanation:
Given:
Total length of the tape is, 
m
Total time of run is, 
hours
We know, 1 hour = 3600 s
So, 2.1 hours = 2.1 × 3600 = 7560 s
So, total time of run is, 
s
Inner radius is, 
Outer radius is, 
Now, linear speed of the tape is, 
Let the same angular speed be 
.
Now, average radius of the reel is given as the sum of the two radii divided by 2.
So, average radius is, 
Now, common angular speed is given as the ratio of linear speed and average radius of the tape. So,
Therefore, the common angular speed of the reels is 1.37 rad/s.

Explanation:
Sound waves can be used in a similar way to "see" things. After turning on a sound source, we can look at the pattern of reflected sound waves that bounce back to us. Our own ears and brain don't process sound into mental pictures.
