A medium is known as denser if the velocity of ray in that phase is fewer than the speed of the wave in other phase.
In comparison to air velocity of sound is main in water, as water is rarer phase for sound waves w.r.t. air. But it is not right for light (EM-waves). For light rays water is denser medium w.r.t. air.
Vectors Representing Forces A force can be represented by a vector (drawn as an arrow). The arrow's length is related to the size of the force and the arrow's direction shows y

We all know that some astronaut had landed in the moon to check out how''s going on the moon. But why only a few astronaut? People created the Apollo and they made it. They sent so
Q. Illustrate is negative mass antimatter? Answer:- It is false there is really no such thing as negative mass. Yet antimatter has mass which is always a positive (that is
Interference of Rectangular Pulses: Two rectangular wave pulses are on a stretched string traveling toward each other. Each pulse is traveling with a speed of 1.00 mm/s. If the lea
If the velocity of the box in problem 10 was 5.0 m/s at time zero, what will be its speed after 0.50 s? How far will it travel in that time interval?
From top of a tower a stone is thrown up and it reaches the ground in time t1. A second stone is thrown down with the same speed and it reaches the ground in t2. A third stone is r

Illustrate how temperature measured in fiber optic sensor. Temperature can be measured via using a fiber which has evanescent loss which varies along with temperature. In the f
How CPH takes spin and converts to graviton? Answer- A CPH Principle says a CPH moves with constant speed as Vc, Vc>c in any inertial frame and any space, therefore that
