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: The amplitude is 0. (assuming that the amplitude ot both initial waves is the same)
Explanation:
When two monochromatic light waves of the same wavelength and same amplitude undergo destructive interference, means that the peak of one of the waves coincides with the trough of the other, so the waves "cancel" each other in that point in space.
Then if two light waves undergo destructive interference, the amplitude of the resultant wave in that particular point is 0.
Answer: You can betterly understand what's around you and how it works
Answer:
v = 478.26 km/h
Explanation:
The question is "find in km.h the speed of a tiger that runs 550 km in 69min"
Distance, d = 550 km
Time, t = 69 min = 1.15 h
We need to find the speed of the tiger. The speed of an object is equal to the total distance covered divided by time taken. So,
So, the speed of the tiger is 478.26 km/h.
I believe it would be orthoclase feldspar, quartz, micas, and amphiboles are the most abundant in granite.<span />
