∙ 14y agoAs an object approaches a concave mirror, the reflection will get a bit wider and longer. If the image is in the middle of the mirror and the object closes directly toward the mirror, the location of the image will still be the middle of that mirror. But, as mentioned, the image will be taking up more room on its sides (getting wider) and at its top and bottom (getting longer). Grab a piece of aluminum foil and create a small experiment using the shiny side of the foil as your mirror! Piece of cake, and real world science in action!

∙ 11y agoAs the object is far away then its image will be at the principal focus of the concave mirror
As the object comes towards the mirror then its image would move away from the mirror with magnified image
When it is at the focus then image will be at infinity so not caught on a screen but could be seen by our eyes
When the object is in between focus and mirror then a virtual but erect and magnified image is formed.
Same way it cannot be caught on a screen but could be seen in the mirror. Hence it is used as a shaving mirror.

∙ 8y agoThere are 5 different possibilities:
- if the object is beyond the centre of curvature of the mirror (C), then the image is smaller and inverted;
- if the object is at C, then the image is the same size and inverted;
- if the object is between C and the focus of the mirror (F), then the image is larger and inverted;
- if the object is at F, then there is no image;
- if the object is between F and the mirror, then the image is larger and the right side up.

Why do you use convex mirror as rear view mirror?
As it shows a larger part of area in a smaller and nearer way.
Which light rays striking a concave mirror are reflected so that they pass through the focal point?
The tendency in case of concave lens would be diverging one. When parallel rays fall one side of the concave lens then due to divergence they appear to come, note down that "they appear to come" from a point on the same side. And this point is named as the virtual focus of the concave lens. Now as a ray passes through this virtual focal point that will be definitely a diverging one. Now due to diverging action of the lens, that ray will be further diverged and that will appear to come from a virtual point on the same side and some what nearer to the concave lens. Hence the image will be virtual and diminished and erect one.
What is the difference between convex and concave lenses?
The expressions relate to the shape of the surfaces of the lens. Concave means that the surface is like the inside of a sphere, convex means that it looks like the outside surface of a sphere. A lens has two surfaces. Most often the spectacle lens are bent away from the eye: the nearer surface is concave and the outside surface is convex.
What will happen to value of g if compound pendulum is taken nearer to the centre of the earth?
The acceleration of gravity decreases as the observation point is taken deeper beneath the surface of the Earth, but it's not the location of the compound pendulum that's responsible for the decrease.
Why does the coin appear to be nearer the surface of water?
due to refraction of light
How does the images change in its size and location as the object comes nearer the convex mirror?

Use of convex mirror?
For a wider field of view in the reflection. In the middle of the mirror, the mirror is facing directly towards you. But nearer the edges it is tilted to the side or above and so you can see things that you would have to turn or tilt an ordinary flat mirror to see.
Why do you use convex mirror as rear view mirror?
As it shows a larger part of area in a smaller and nearer way.
What is the difference between parabolic and concave mirrors?
In the case of concave mirrors parallel rays, parallel to the principal axis and incident near the pole(axial rays), after reflection will converge to the principal focus.Rays reflected from the marginal portions of the mirror(marginal rays) will converge to points nearer than the focus. Due to this the image formed by a concave mirror of large aperture will be blurred. This defect is called spherical aberration. This defect can be overcome by using parabolic mirrors. In a parabolic mirror all the rays, axial rays as well as the marginal rays, incidenting on it after reflection will converge to the same principal focus. This is due to the geometric property of the parabola, that is parabola allows only one focus.Hence in a parabolic mirror there is no spherical aberration and the image will be sharp and clear.
Why is it written on the side rear view mirror that objects are nearer than they appear?
Because they are.
Does mirror have a long vowel sound?
No. The I is a short (rhotic) I and an unstressed O. It rhymes with nearer.

What rhymes with mirror?
Deer, dear, seer, veer, mere, near, peer, steer, clear, severe, fear, ear, hear, here, jeer, queer, smear, tear, nearer, terror, error, cheer
Why do fish in the aquarium appear nearer the surface than they really ar?
The light is refracted through the water surface/skin, which is concave and called a meniscus. This curve works like a close-up lens and magnifies the fish.
On a seesaw does the heavy person need to sit nearer the end or nearer the middle?
the heaviest person would have to sit nearer the middle
