<u>Answer:</u> The angle of diffraction is 0.498°
<u>Explanation:</u>
To calculate the angle of diffraction, we use the equation given by Bragg, which is:
where,
n = order of diffraction = 3
= wavelength of the light =
(Conversion factor:
)
d = spacing between the crystal planes = 0.100 mm = (Conversion factor: 1 m = 1000 mm)
= angle of diffraction = ?
Putting values in above equation:
Hence, the angle of diffraction is 0.498°
Answer:
a)188.65m
b)154.35m
c)243.7m
Explanation:
Given data:
(a) The distance from the kicker to each of the 2 spectators is given by:
where,
v= speed of sound
=time taken for the sound waves to reach the ears
m
(b)
where,
v= speed of sound
=time taken for the sound waves to reach the ears
(c)As the angle b/w slight lines from the two spectators to the player is right angle,
hypotenuse=the distance b/w 2 spectators
and, the slight lines are the other 2 lines
