Lorentz was the first to obtain the equations which relate the space and time coordinate of two frames of reference moving with a constant velocity with reference to each other and obeying the postulate of STR giving by Einstein, these equations are called Lorentz Transformation Equation.
Let us consider two observer O and O' in frame of references S and S'. The frame S' is moving with a uniform velocity v with reference to frame S, in + x direction. At time (t=0) observer O and O' are at the origin of the frame of reference S and S'.
The power distribute to a 15 watt light bulb in normal operation is 15 watts. In normal operation how greatly energy is delivered to such a bulb in an hour? Feedback:
Q. The Rydberg's constant for hydrogen is 1.097 X 10 7 ms -1 . Calculate the shortest wavelength limit of Lyman series. Data : R = 1.097 × 10 7 m -1 For small wavelen
THE BASIC CAPACITOR If we have two metal plates close together, but separated by an insulator or dielectric (which could be air) and we apply a voltage across them, electrons a
Two waves of equal frequency have amplitudes 2 units and 3 units respectively. When they superpose coherently the intensity of the resultant wave is I 1 . The intens
Unit Vectors A unit vector is a vector of unit length. A easy animation of unit vectors and vector addition. A unit vector is a vector of length 1, sometimes also called a dir
A toy truck is pushed across a table 0.80 m north, and pulled back across the table 0.80 m south. If a constant horizontal force of 15 N was applied in both directions. what
What is curvilinear motion? Basically, it's any motion that's produced or bounded by curved -- as opposed to straight -- lines. In high school, curvilinear motion is usually
Define the Intensity of the laser in short. Intensity: a. Lasers are intense and bright light sources. It is due to coherence and directionality. b. The intensity is e
Determine the weight of a body. Principle: When a spring is fixed at one end and a force is applied to the other end the stretching of the spring is proportional to the applie
