Chapter 3, Problem 1RCQ
What is Newton’s first law of motion?
Expert Solution & Answer
To determine
To know:
Newton’s first law of motion.
Answer to Problem 1RCQ
Solution:
Every object continues to be in its state of rest or its state of motion with uniform speed in the same direction (or in a straight line), unless it is acted upon by a nonzero or unbalanced force.
Explanation of Solution
We know that inertia is an inherent property of any object due to which it has tendency to resist any change in its state of motion. For ex: a book kept on table is in state of rest. In other words, it is stationary or it has zero speed. It will neither change its position nor its speed, i.e. it will not move, unless someone applies a force on it.
On the other hand, if an object is moving with a uniform speed in a certain direction, then it will continue to move without changing either its speed or its direction, unless some force acts on it. For ex: an object moving with speed
Since Newton’s first law of motion is directly related to inertia of the object, therefore, this law is also called as Law of Inertia.

Three slits, each separated from its neighbor by d = 0.06 mm, are illuminated by a coherent light source of
wavelength 550 nm. The slits are extremely narrow. A screen is located L = 2.5 m from the slits. The
intensity on the centerline is 0.05 W. Consider a location on the screen x = 1.72 cm from the centerline.
a) Draw the phasors, according to the phasor model for the addition of harmonic waves, appropriate for this
location.
b) From the phasor diagram, calculate the intensity of light at this location.
A Jamin interferometer is a device for measuring or for comparing the indices of refraction of gases. A beam
of monochromatic light is split into two parts, each of which is directed along the axis of a separate cylindrical
tube before being recombined into a single beam that is viewed through a telescope. Suppose we are given the
following,
•
Length of each tube is L = 0.4 m.
• λ= 598 nm.
Both tubes are initially evacuated, and constructive interference is observed in the center of the field of view. As
air is slowly let into one of the tubes, the central field of view changes dark and back to bright a total of 198
times.
(a) What is the index of refraction for air?
(b) If the fringes can be counted to ±0.25 fringe, where one fringe is equivalent to one complete cycle of
intensity variation at the center of the field of view, to what accuracy can the index of refraction of air be
determined by this experiment?
