For a series LCR circuit, I vs $$\omega$$ curve is shown :

(a) To the left of $$\omega$$_r, the circuit is mainly capacitive.

(b) To the left of $$\omega$$_r, the circuit is mainly inductive.

(c) At $$\omega$$_r, impedance of the circuit is equal to the resistance of the circuit.

(d) At $$\omega$$_r, impedance of the circuit is 0.

Choose the most appropriate answer from the options given below :

An EM wave propagating in x-direction has a wavelength of 8 mm. The electric field vibrating y-direction has maximum magnitude of 60 Vm^$$-$$1. Choose the correct equations for electric and magnetic fields if the EM wave is propagating in vacuum :

If L, C and R are the self inductance, capacitance and resistance respectively, which of the following does not have the dimension of time?

Given below are two statements :

Statement I : A time varying electric field is a source of changing magnetic field and vice-versa. Thus a disturbance in electric or magnetic field creates EM waves.

Statement II : In a material medium, the EM wave travels with speed $$v = {1 \over {\sqrt {{\mu _0}{ \in _0}} }}$$. In the light of the above statements, choose the correct answer from the options given below.
