Question

when we look at the seashores from afar, we see that some parts are light blue and some parts are dark blue...... How does this phenomenon occur?

Answer 1

Answer:

The seahorse looks blue because red, orange and yellow (long wavelength light) are absorbed more strongly by water than is blue (short wavelength light). So when white light from the sun enters the ocean, it is mostly the blue that gets returned. Same reason the sky is blue.
