It is a mathematical explanation of the disturbance prepared by a ray. For a string, the wave function is a distance for sound rays. It is a density or pressure fluctuation while for light waves it is electric / magnetic field.
Now let us take a one dimensional wave traveling with reference to x-axis. During ray motion, a particle with equilibrium position x is displaced some distance y in the direction perpendicular to the x-axis. In that part y is a function of position (x) and time (t).
A concave lens when given in air has a focal length of 0.4 m and has a refractive index of 3/2. Evaluate its focal length when immersed in water of refractive index 4/3?
Cart and The Brick Collisions among objects are governed through laws of momentum and energy. While a collision occurs in an isolated system, a total momentum of the system of
Difference among sound and light waves: (i) For propagation of sound rays material phase is required but no material medium is needed for light waves. (ii)Sound rays are long
A long cylindrical volume haves a uniformly distributed charge of density ρ and radius R. Determine the electric field at a point P inside the cylindrical volume at a distance x (x
How theta between plane of the coil and magnetic field remains constant
What is Heat? We now have several scales for measuring temperature, but first let's ask, “Is temperature the same as heat?” If I add heat to a pot of water, the water's temperatu
How are amps and watts related? In a nutshell, the power (measured in watts) dissipated by a resistance is directly proportional to the square of the current (measured in amper
It is the ratio of the internal electric field induced by the charges on the surface on the dielectric when an external field applied to the polarization of the dielectric.
according to the first law of thermodynamics , obtain the relationship between specific hears of gases
