<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°
Circular motion is what an object has if it is moving around and around and around and around and around and around and around and around and around in a path that is a circle.
Angle, θ2 at which the light leaves mirror 2 is 56°
<u>Explanation:</u>
Given-
θ1 = 64°
So, α will also be 64°
According to the figure:
α + β = 90°
So,
β = 90° - α
= 90° - 64°
= 26°
β + γ + 120° = 180°
γ = 180° - 120° - β
γ = 180° - 120° - 26°
γ = 34°
γ + δ = 90°
δ = 90° - γ
δ = 90° - 34°
δ = 56°
According to the law of reflection,
angle of incidence = angle of reflection
θ2 = δ = 56°
Therefore, angle θ2 at which the light leaves mirror 2 is 56°
Answer:
its unit is Ohm
Explanation:
Resistance means material which resist the passing current through it and the value of resistance says how much the material is resisting the current and it temperature dependent and the unit is Ohm.
