An unpolarized light shines on an object that is placed below a crystal. When an observer looks at the object through the crystal there are two images present. Explain how that can happen using the information learned in optics and e-m radiation

See explanation

Explanation:

Solution:-

- light reflected through calcite crystals difference occurs due to the polarity of the light passing through the crystal. Daylight is composed of light vibrating in all planes, whereas reflected light is often restricted to a single plane that is parallel to the surface from which the light is reflected.

- Light that is reflected from the flat surface of a dielectric (or insulating) material is often partially polarized, with the electric vectors of the reflected light vibrating in a plane that is parallel to the surface of the material.

- light waves that have the electric field vectors parallel to the surface are reflected to a greater degree than those with different orientations.

total distance travelled = 60 miles

total time taken =1.5 hours

average speed = total distance / total time

60 / 1.5

= 40

therefore, average speed = 40 m/h
