Question

You and your dog are walking along a pond. Your dog looks into the still water and is startled to see its reflection. Which phenomenon is responsible for the appearance of the dog’s reflection on the water's surface? A. diffraction of water waves B. reflection of lightwaves C. refraction of lightwaves D. reflection of water waves E. refraction of water waves

Answer 1

You just identified the image as a "reflection", so it's a pretty good bet that
the phenomenon involves reflection somehow.

Your dog can see his reflection in a mirror inside the house just as easily
as in the surface of the pond.  My dogs do it all the time.  The phenomenon
doesn't require water.

It's reflection of light waves.

Answer 2

Answer: Option B: Reflection of light waves.

Explanation:

Reflection occurs when light waves bounce back from any surface. When the dog looks into the still water, it could see its own reflection. This is because the light waves incident from dog gets reflected on the surface of water and dog is able to see its own reflection.

Hence, the phenomenon responsible for appearance of dog's reflection on surface of water is reflection of light waves.
