Angle of incidence 15.0° 30.0 45.0° 60.0° 75.0° Angle of refraction 9.9° 19.5° 28.2° 35.3° 40.1° A student is reviewing the data in the given table, listing the angle of incidence and angle of refraction of a laser beam from air into a block of plastic. The student is trying to answer the question, "is the index of refraction of the plastic greater than that of air?" The student does not have a calculator on hand to find the sines of the angles. Can the student answer the question based on just examining the values of the angles in the table, and why or why not? that passes

Displacement, Velocity and Acceleration

In classical mechanics, kinematics deals with the motion of a particle. It deals only with the position, velocity, acceleration, and displacement of a particle. It has no concern about the source of motion.

Linear Displacement

The term "displacement" refers to when something shifts away from its original "location," and "linear" refers to a straight line. As a result, “Linear Displacement” can be described as the movement of an object in a straight line along a single axis, for example, from side to side or up and down. Non-contact sensors such as LVDTs and other linear location sensors can calculate linear displacement. Non-contact sensors such as LVDTs and other linear location sensors can calculate linear displacement. Linear displacement is usually measured in millimeters or inches and may be positive or negative.
