Relation among velocity wavelength and Frequency:
Consider a wave of wavelength , frequency f and travelling with velocity v.
The distance travel by the sound wave during the interval in which the particle of the medium complete single vibration is known as wavelength and the time taken by the wave is known as time period
Archimedes' principle A body which is submerged into a fluid is buoyed up through a force equal in magnitude to the weight of the fluid which is displaced, and directed upward

While travelling in a straight line, a car uniformly alters its speed from 50 kilometres per hour to 110 kilometres per hour in 5 seconds. The acceleration of the car during
The Phenomenon of producing a transverse emf in a current carrying conductor on applying a magnetic field perpendicular to the direction of the current is known as Hall effect.
If the speed of light were smaller than it is, would relativistic phenomena be more or less conspicuous than they are now? All else being similar, involving the rates of the ch
