Question

Take a shiny soup spoon and look at your reflection in the side that holds the soup. What does it look like? Can you explain this, using the terms "angle of incidence" and "angle of reflection"? Now turn the spoon over and look at your reflection in the back of it. What does it look like now?

Answer 1

Answer:

When observing the image inside a spoon, the image seems to be bent or cut, because the rays of light deviate with a  certain angle of incidence, since they travel slower when passing from the air, where there are less particles, to the liquid, where there are more particles .

When turning the spoon a specular reflection is observed, it is when the surfaces are polished, the light rays are reflected with and angle of reflection in only one direction and in an orderly manner. This is why images are formed that look like copies of objects.

Explanation:

Reflection and refraction of waves are two phenomena that occur when a wave that propagates in a certain medium meets a separation surface with another medium.

Reflection is the change in direction that a wave experiences when it comes into contact with the surface that separates two media while returning to the point where it originated. Refraction is the change of direction and speed that a wave undergoes obliquely on a surface that separates two media with different refractive indices.

• Reflection occurs when light hits a surface and part of it changes direction and returns in the same direction to the point from which it left. This phenomenon also occurs with sound waves.

• Refraction occurs when the invisible light passes through a transparent material, changes direction and passes obliquely between two media with different refractive index.

• In reflection light travels in the same medium.

• In refraction, light travels from one medium to another.
