A plane monochromatic wave travelling in a homogeneous medium goes into a denser medium. What are the changes in (i) Frequency (ii) amplitude (iii) speed of propagation & (iv) Phase of transmitted and reflected wave in comparison with the corresponding properties of the incident wave.
For the same leg strength / jumping technique weight affects how far one can jump. Acceleration = Force / Mass With more mass you can't accelerate yourself as much when you j
The speed at which a wave propagates down a string is 300 meters per second. If the frequency of this wave is 150 Hertz, what is the wavelength of this wave? Ans: The wavel
How are fiber optic made? The actual process varies significantly from one manufacturer to other. In essence, a huge cylinder of core is made off high purity material, an eleme
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
The force is in Newton The buoyant (upward) force exerted by water on a submerged object is given by the formula F= ?Vg, where ? is the density of water (1.0 x 10 3 kg/m 3 ),
A ray of white light in air passes by a glass plate. Refraction takes place. The direction in which the light is travelling changes. For what colour of light is the alteration in d
Does weight affect how far you jump? For the same leg strength / jumping method, weight affects how far one can jump. Acceleration = Force / Mass With more mass, you can
a freely falling object near the Earth''s surface has constant?
NEWTON'S FIRST LAW OF MOTION: This law states that "A body at rest will remain at rest and a body moving with uniform velocity will carry on doing so, until acted on by some un
The distance at any time because of any value of pulse meeting concurrently at a position in a medium is the vector addition of the individual distances due every one of the ray at
