What does this say about the relative speeds of light in the glass and in the oil?

What does this say about the relative speeds of light in the glass and in the oil?

What does this say about the relative speeds of light in the glass and in the oil? The speeds of light in the glass rod and in the oil are the same.

What caused the difference in the projection of your reflection on the concave and convex side of the spoon explain?

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. A convex mirror makes what you see smaller and more so as you look closer to the edges.

Why a concave mirror does not reflect all rays parallel to its optical axis through its focal point?

Incident rays parallel to the optical axis are reflected from the mirror and seem to originate from point F at focal length f behind the mirror. Thus, the focal point is virtual because no real rays actually pass through it; they only appear to originate from it. Reflection in a concave mirror.

What is the name of the phenomenon when light changes its direction after hitting on a shiny surface?

Refraction is the bending of light rays. Normally, light travels in a straight line, and changes direction and speed when it passes from one transparent medium to another, such as from air into glass.

When light rays pass through the lens This phenomenon is called?

Refraction is the bending of light (it also happens with sound, water and other waves) as it passes from one transparent substance into another. This bending by refraction makes it possible for us to have lenses, magnifying glasses, prisms and rainbows.

What is the relationship between refraction and the speed of light?

The relationship between refraction and the speed of light is indirect, the slower the speed of light the more refraction will occur.

What does the front side of the spoon represent?

(a) Back side of the spoon has a curved outwards reflecting surface and is therefore a Convex surface. (b) Front side of the spoon has an inwards reflecting curve and is therefore a Concave surface.

What are two behaviors of incident rays reflecting off of a concave mirror?

They are: Any incident ray traveling parallel to the principal axis on the way to the mirror will pass through the focal point upon reflection. Any incident ray passing through the focal point on the way to the mirror will travel parallel to the principal axis upon reflection.

How are parallel light rays reflected by a convex mirror?

When parallel light rays hit a convex mirror they reflect outwards and travel directly away from an imaginary focal point (F). Each individual ray is still reflecting at the same angle as it hits that small part of the surface.

What would be the angle between the light ray and its reflected ray?

The angle between the incident ray and the normal is known as the angle of incidence. The angle between the reflected ray and the normal is known as the angle of reflection.

What is mean by reflected ray?

A ray of light or another form of radiant energy that is thrown back from a nonpermeable or nonabsorbing surface is called reflected ray. The ray of light that bounces back from the surface of reflection is called the reflected ray. All the rays the incident, normal and reflected lie on the same plane.

What does the All Seeing Eye symbol mean?

The all-seeing eye is there, silently watching. But what does it mean? Also known as the Eye of Providence, the all-seeing eye is the symbol of a single eye encompassed by a triangle, often surrounded by shining rays of light. Its origins can be traced back to ancient Egypt and the Eye of Horus, and it usually holds a religious significance.

What happens when a ray passes through a mirror?

Any incident ray traveling parallel to the principal axis on the way to the mirror will pass through the focal point upon reflection. Any incident ray passing through the focal point on the way to the mirror will travel parallel to the principal axis upon reflection.

What happens if you draw third pair of rays?

If your were to draw a third pair of incident and reflected rays, then the third reflected ray would also pass through this point. This is merely the point where all light from the top of the object would intersect upon reflecting off the mirror.

How does a ray travel through a focal point?

The ray that passes through the focal point on the way to the mirror will reflect and travel parallel to the principal axis. Use a straight edge to accurately draw its path. The ray that traveled parallel to the principal axis on the way to the mirror will reflect and travel through the focal point.
