what is the angle of incidence when the refracted and the reflected ray are parallel to one another? does this angle depend on the wavelength of light?
Ans) The angle of incidence is zero an it depend onthe wave lenght of the light.
What affect does electricity have on soil? Electrical current and ions can cause definite molecules (and moisture) to adhere to soil. Large amounts of current, like a lightning
plz derive a equation to magnetic force between short magnetic dipoles at distance apart?

Eddy currents can be briefly explained as currents produced due to induced emf in the form of eddies or ripples. Hysteresis laws mainly consists of 2 topics retentivity and coerci
A standing wave is formed on a tightly stretched string. The distance between a node and an antinode is: w) 1/8 wavelength x) 1/4 wavelength y) 1/2 wavelength
Three similar coils, each having a resistance of 8 and an inductive reactance of 8 are connected (a) in star and (b) in delta, across a 415V, 3-phase supply. Measure for
What is electric flux? Write its S.I. units. Using Gauss's theorem, assume an expression for the electric field at a point because of a uniformly charged infinite plane sheet.
A 20 Ω non-reactive resistor is connected in series with a coil of inductance 80mH and negligible resistance. The combined circuit is connected to a 200V, 50Hz supply. Calcula
Sol: The incident angle is 45 because the angle of reflection and angle of incident is equal.
