Interference of Light

The word "constructive" signifies addition in interference. Constructive interference occurs when the path of the waves that start from the slit differs by 1 entire wavelength or in the intervals of the same. Hence, the waves that are presented on the screen are in phase (crest to crest/trough to trough). The waves interfering constructively forms bright fringes on the screen.

Question

How is the difference in paths taken by two originally in-phase light waves related to whether they interfere constructively or
destructively? How can this be affected by reflection? By refraction?

(c) Why does light from a clear blue portion of the sky show a rise and fall of intensity when viewed through a polaroid which is rotated? Explain by drawing the necessary diagram.
The fact that light can be polarized and sound cannot be polarized can be best explained by which? Light travels much faster than sound. O Light is a transverse wave and sound is not. O Light travels much slower than sound. O Light is a longitudinal wave, and sound is not.
Light will not pass through a pair of Polaroid sheets when they are aligned perpendicularly. However, if a third Polaroid is sandwiched between the two with its alignment halfway between the alignments of the other two (that is, with its axis making a 45° angle with each of the other two alignment axes), some light does get through. Why?
When light is incident on an interface between two materials, the angle of therefracted ray depends on the wavelength, but the angle of the reflected ray does not.Why should this be true?
