Express epsilon_i, in the phasor domain, and determine theta_i, (from the direction of propagation) and theta_t, (from Snell's law). Find the reflected and transmitted electric fields. E_r, and E_t For what angle theta_i to does the reflected field contain only the TE component? Recalculate E and E for this case.

hi there!

the answer will be d: 2

the correct option is 2.

step-by-step explanation:

according to the given information triangle abc is a right angle triangle with right angle at a. segment ab is 5 and segment ac is 7. point d is on segment bc and angles adb and adc are right angles.

it is given that triangles abd, cad, and cba are similar.

two triangles are similar if their corresponding sides are proportional.

in triangle cba, using pythagoras theorem

                      )

triangle abd and cba are similar,

                            (2)

triangle cad and cba are similar,

                      )

using (1), (2) and (3), we get

hence proved.

therefore option 2 is correct.
