How a spoon can be both a concave and a convex mirror?

​ A shiny spoon is like a mirror – only curved. Since the surface is completely smooth, it gives a mirror image – a specular reflection. But since it’s curved, the rays of light are reflected in different directions depending on where they hit the spoon. ​​ This side that bulges out is called the convex side.

Is a spoon both concave and convex?

Metal spoons are both convex (curves out) and concave (curves in) mirrors. When you see an image in a flat mirror, the light waves bounce straight back at you. This is called reflection. But when curved, a mirror bends the light rays and distorts the image; this is called “refraction.”

Which sides of the spoons are behaving like a concave and convex mirror Why?

The inner surface of a spoon acts as a concave mirror and the outer surface of the spoon acts as a convex mirror. When you see yourself in a spoon which is like a concave mirror, the light rays from your face fall on the top of the spoon and get reflected downwards.

Is the front of a spoon concave or convex?

The curved surfaces of a spoon act like mirrors. The front part of the spoon is concave while the back side of the spoon is convex.

Why does a spoon reflect upside down?

Unlike a flat mirror, the curved surface of the spoon’s bowl bounces incoming rays back towards a central focus point lying between your face and the centre of the spoon’s. In passing through this point, rays from the upper part of your face are reflected downward, while those from the lower part are reflected upward.

What type of mirror is spoon?

convex mirror
The back of a spoon is a convex mirror. The convex shape has an outward curve.

Why does my face look upside down in a spoon?

Is a spoon a concave mirror?

The inner surface of a spoon acts like a concave mirror, while its outer surface acts like a convex mirror.

Why is the convex of the spoon upright?

Convex mirrors makes the light rays focus together. The inside focus is upright and larger in view, like the side mirror on a car. These types of mirrors disort the images they make. A convex mirror like the front of the spoon, makes an image that can be small or large, and right side up or upside down.

Are the sides of a spoon concave or convex mirrors?

I recently saw a lecture that said the following regarding the sides of a spoon as concave/convex mirrors: The concave inside of the spoon must be a positive focal length mirror because it would take normally incident rays and bend them towards the axis.

Why is the normal of a curved spoon different from a mirror?

But since the spoon is curved, the normal is different at different points. A convex mirror gathers the rays of light together from a larger area than an ordinary flat mirror.

What is the convex side of a spoon?

This side that bulges out is called the convex side. The rays of light bounce off the spoon, and at the exact point that a ray hits the surface, its angle of incidence is the same as the angle of reflection. But since the spoon is curved, the normal is different at different points.

Is the convex outside of the spoon a negative focal length mirror?

Conversely, the convex outside of the spoon must be a negative focal length mirror because it bends rays away from the axis. I immediately found this perplexing, since my understanding is that it precisely is the opposite.
