Match List-I (Electromagnetic wave type) with List-II (Its association/application) and select the correct option from the choice given below the lists :
A long cylindrical shell carries positive surface charge σ in the upper half and negative surface charge −σ in the lower half. The electric field lines around the cylinder will look like figure given in : (figure are schematic and not drawn to scale)
On a hot summer night, the refractive index of air is smallest near the ground and increases with height from the ground. When a light beam is directed horizontally, the Huygens' principle leads us to conclude that as it travels, the light beam :
Two charges, each equal to q, are kept at x = ?a and x = a on the x-axis. A particle of mass m and charge q0=2q is placed at the origin. If charge q0 is given a small displacement (y a) along the y-axis, the net force acting on the particle is proportional to:
