you observe your mom
use a mirror to change the path of light.
Glass and perspex prisms, and mirrors can change the path of light. Try to look up the law of reflection on google, it should be a great help!

it refracts closer to the medium
Light can be refracted when it passes from one medium to another with a different density, causing its speed to change. The change in speed leads to a change in the light's direction, causing it to bend. This bending is what we observe as refraction.
Light waves travel in straight lines unless they encounter a medium density change or are reflected or refracted by a surface. This results in bending or scattering of the light waves along their path.
light takes a straight path.
The speed of light is constant in its reference plane. You could never observe light moving more slowly, except when it refracts through a transparent medium.
how does water affect light path
Light travels in a straight line until it encounters a medium that causes it to change direction, such as reflection or refraction. It moves at a speed of about 186,282 miles per second in a vacuum. The path of light can be altered by transparent or reflective surfaces it encounters.
refraction
Light travels in a straight line due to the wave nature of light, where it follows the path of least resistance. This is known as the principle of least time, where light takes the shortest path between two points. Additionally, light can be bent or refracted when it encounters a change in medium, such as passing through air to glass, which causes a change in its speed and direction.
