You can tell whether velocity is changing because velocity is the rate/speed of motion of something in a direction either it increase or decrease in the speed or a change in its direction that will causes its velocity to change.
Explanation:
The equation of grating is given by :
Here,
(a+b) is called grating element
N is the number of slits per unit length,
n is the order
is the wavelength of light used
is the diffraction angle
Here, we need to write the effect on the interference pattern produced by a grating if the number of slits per unit length is increased. If the number of slits per unit length increases, the grating element decreases such that the angle of diffraction increases. Hence, the interference pattern shrinks.
Answer:
Thus, the change in the weight of the person is 1.6N , option c is correct.
