Longitudinal Waves and Tuning Forks
Sound waves are generates through vibrating objects. Whether it is the sound of a person's voice, the sound of a piano and the sound of a trombone or the sound of a physics book slamming to the floor and the source of the sound is forever a vibrating object.
ACCELERATION DUE TO GRAVITY. In the absence of air resistance, all objects in free fall near the surface of the earth move in the direction of the earth with a uniform accelera
why the reflective index of cladding is lower then in core of a fiber optic?
INERTIAL FRAME OF REFERENCE: "A frame of reference which is not being accelerated and it might be at rest or moving with uniform velocity is known as inertial frame of referen
COHERENCE : 1) Visible light energy is emitted when the excited electrons in atoms undergo transitions to the ground state. 2) In ordinary light sources, these transitions
Could the light along a side emitting optic be a totally homogeneous? Regardless of the assurances of several manufacturers, it is a total impossibility since it would clash wi

FORCE: "Force is that agency which causes a body to alter its state of motion or rest". It is denoted by F ?
Q. If an object isn't moving, no external force acts on it. No it is always not true, there would be balanced forces which cancel each other out leaving no net force. Example:
