A teacher took the picture below of a pond near the school on a cool, still autumn morning.

The teacher showed the students five different models, seen below, of what could happen when light interacts with a surface and asked them to select the model that demonstrates how the image is formed in the pond and provide an explanation for the model.

Which of the following is the BEST explanation for the formation of the image in the pond.



A.
The correct model is W because light waves bounced off the surface of the pond producing an image.

B.
The correct model is Z because light waves were absorbed by the water of the pond producing an image.

C.
The correct model is X because light waves were refracted and the bending of the waves produced the image on the pond.

D.
The correct model is V because light waves were transmitted and the wavelenghts passing through the water produced the image on the pond.

To select the best explanation for how the image is formed in the pond, we need to consider how light interacts with a still water surface.

A still pond typically reflects light, which allows us to see the image of the surroundings, such as trees, sky, and other objects being mirrored on the water's surface. Based on the descriptions given:

A. Model W suggests that light waves bounced off the surface of the pond, producing an image. This aligns with the behavior of light reflecting off a smooth surface, such as water.

B. Model Z states that light waves were absorbed by the water, which would not produce a visible image, as absorption would prevent the light from reflecting back to our eyes.

C. Model X indicates that light waves were refracted, which typically involves the bending of light as it passes through different mediums. However, while refraction occurs at the water surface, it is primarily reflection that allows us to see an image of the surroundings.

D. Model V suggests that light waves were transmitted through the water, but this process does not produce an image; instead, it allows light to pass without forming a reflective image on the surface.

Given these considerations, the BEST explanation for the formation of the image in the pond is:

A. The correct model is W because light waves bounced off the surface of the pond producing an image.
