"The Mirror Lake"
The water in the lake is acting as a mirror of the mountains. The light that the sun gives off, bounces off the mountains and onto the water. From there, it is reflected back up and into the lens of the camera or eyes of anyone who is looking at it. Reflection involves the change in direction of the waves as they bounce off a barrier, which in this case is the water surface. The incident ray hits the water’s surface at a certain angle from the normal line that is known as the angle of incidence. The light wave then bounces off as the reflected ray at an equal angle from the normal line called the angle of reflection. The angle of the mountains to the water is the same as the angle from the camera to the water so the camera is able to capture the reflection of the mountains. One can also see the waves in the water. This is caused by the light wind pushing against the surface of the water. As the wind blows, pressure and friction forces unsettle the equilibrium of the water surface by transferring energy into the surface, creating waves.
