i. ii. iii. iv. V. Regarding the phenomenon of light, make specific reference to the case of water waves or sound, in order to explain why early physicists proposed the existence of the so called ether frame of reference. [5 marks] What are the fundamental matter properties responsible for the following matter interactions, the electric force, the gravitational force, the magnetic force? Also, explain what the term action across the void means in the subject of physics. [3 marks] Maxwell's four equations of electromagnetic theory are V.E=, V.B = 0, V×Ē= ав - and V × B = µ‚Ï + μ₂². Explain the physical mechanism implied in the second HJ H²0² and the last equations in these set of equations. at [2 marks] A certain mathematical analysis upon these equations, considered in free space, results in a²Ē the following two separate equations for the electric and magnetic fields: V²Ē = µo²o 9² 0²B and V²B = Hoo Provide further arguments to reveal that the two fields move through space in a wave form. Further, if the permeability of free space and the permittivity of free space have the values 1.257 x 10-6TmA-¹ and 8.854 x 10-12C²N-¹m-2 respectively, determine the value of the speed of these waves in free space. [2 + 2 marks] Provide arguments based on the value you found for this speed, together with a subsequent conclusion and confirmation that light is a form of an electromagnetic wave, in order to nullify the hypothesis mentioned in (i) above about the ethereal frame of reference.
