Correct option is
C
3 cm
RI=apparent depthreal depth
Substituting, 34=apparentdepth12
Therefore, apparent depth=412×3=9
The height by which it appears to be raised is 12−9=3cm

A tank is filled with water to a height of 12.5 cm. The apparent depth of a needle lying at the bottom of the tank is measured by a microscope to be 9.4 cm. What is the refractive index of water? If water is replaced by a liquid of refractive index 1.63 up to the same height, by what distance would the microscope have to be moved to focus on the needle again?

Its letter C. 5N to the left. Since Jeremy's force in Newtons are higher than Amanda's (in newtons), and since Jeremy's force directs to the left, then the direction of the force will be to the LEFT. Then subtract the higher one to the lower one so that would be: 10N-5N=5N. So it is C. 5N to the left.
Answer:
The wave propagates on the z axis and the polarization is linear on the x axis
Explanation:
Part A
When the two dipole charges oscillate they form a fluctuating wave that propagates in the perpendicular direction, so if the oscillation of the magnetic field is on the axis and the propagation of the wave occurs on the z-axis.
The polarization of the electric wave is equal to the direction of the electric field, therefore as the field oscillates on the x-axis the polarization is also on the x-axis and is linearly polarized.
Part B
The wave propagates on the z axis and the polarization is linear on the x axis
