Explanation:
Whenever the light passes through hole or slit then it tends to bend that is actually a diffraction. It will then made the interference pattern of light and dark bands that due to constructive and destructive interference.
So by using the equation of diffraction,
dsinA = nL
SinA is a geometric component it can be written as,
∵ x is the distance from screen.
∵ y is the half of the width of central maximum.
now by putting the values in mm,
d = 2.15× mm
Answer:
The acceleration of a point on the wheel is 11.43 m/s² acting radially inward.
Explanation:
The centripetal acceleration acts on a body when it is performing a circular motion.
Here, a point on the bicycle is performing circular motion as the rotation of the wheel produces a circular motion.
The centripetal acceleration of a point moving with a velocity and at a distance of
from the axis of rotation is given as:
Here,
∴
Therefore, the acceleration of a point on the wheel is 11.43 m/s² acting radially inward.
