To solve this exercise, it is necessary to apply the concepts on the principle of superposition, specifically on constructive interference,
Constructive interference (light spot) is defined by
Where,
m = The integer m is called the interference order and is the number of wavelengths by which the two paths differ.
d = Distance
For smaller angles ,
From the trigonometric properties it is understood that so the is - in this case - the length measured vertically by reason of distance, that is
Re-arrange to find y,
Replacing our values
PART B) To calculate the intensity it is necessary to find the angle between the previously calculated height and distance in order to calculate the phase angle, in other words,
Therefore phase angle is
The intensity formula would then be given by,
Answer:
Explanation:
The velocity of plane relative to earth is given by:
As the from given data.The velocity of plane relative to air is:
According to relative motion of velocity of the air relative to earth given by:
The magnitude is given as:
Answer:
a= 4.4×10 m/s^2
Explanation:
pressure P = E/c
Where, E = 100 W/m^2 intensity of light
c= speed of light = 3×10^8 m/s
P = 1000/ 3×10^8
P = 3.33×10^(-6) Pa
Force F = P×A
- P is the pressure and c= speed of light
F = 3.33×10^{-6}×6.65×10(-29)
= 2.22×10^{-6}
acceleration a = F/m = 2.22×10^{-6}/ 5.10×10^{-27}
a= 4.4×10 m/s^2
a vector is inclined at 45 degree North of east
so here we can say
here we can say that
East direction is along x direction
North direction is along Y direction
so here the given direction in vector form as
so here the given direction is in vector form shown as above
