Question

4. Which of the following is false about polarization of light? a. It explains the separation of colors in white light by a prism. b. It can arise in reflection or scattering of light. c. The intensity of a light wave by itself does not give any information about the wave's polarization. d. It arises because electric and magnetic fields in waves can have components in two perpendicular directions. 5. Which of the following is false about Maxwell's equations? a. The waves they predict move with velocity 1/VOED b. Coulomb's Law is contained in these equations. c. One consequence of $B dĀ= 0 is that there are no magnetic monopoles. d. Gauss' Law, Ampere's Law, and the Law of Biot-Savart are all contained in these equations. 6. Which of the following is false about a wire carrying current to the right? a. Comparing how the wire looks when viewed from in front of the page or from behind the page and considering what one expects if the current changes direction shows that the radial component of the magnetic field must be zero. b. Since the field must be perpendicular to the current, the component of field parallel to the wire must be zero. c. Application of Ampere's law shows that the component of the field that circles the wire decreases as the inverse of the distance to the wire. d. The law of Biot-Savart cannot be used to calculate the field due to the wire.

Answer 1

(4):(a) It explains the separation of colors in white light by a prism.this statement is false about polarization of light.But this statement true about dispersion of light .

(5):(b) Coulomb's law is contained in Maxwell's equation.This statement is false for Maxwell's equation.

(6):(d) The law of Biot-Savart can not be used to calculate the field due to wire.This statement is false because this law is fundamental to calculate field due to wire.
