For what range of object positions does a concave spherical mirror form a real image? What about a convex spherical mirror?

Short Answer

Expert verified

No, real image never forms any real image of objects

Step by step solution

01

Virtual image

If the object is placed at a distance ofd0from a spherical mirror with a focal length, the distance of image of the object formed by the spherical mirror from the vertex of the spherical mirror is given by:

di=d0·fd0-f

Now, ifdi is positive and the image is real and ifdi is negative then the image is virtual.

02

Convex spherical mirror

Now, we know that convex spherical mirror never forms a real image of the object, hence no mater what range of object or positions concave spherical mirror will never form real image.

Atmospheric haze is due to water droplets or smoke particles (“smog”). Such haze reduces visibility by scattering light so that the light from distant objects becomes randomized and images become indistinct. Explain why visibility through haze can be improved by wearing red-tinted sunglasses, which filter out blue light.

When hot air rises from a radiator or heating duct, objects behind it appear to shimmer or waver. What causes this?

A person looks at his reflection in the concave side of a shiny spoon. Is it right side up or inverted? Does it matter how far his face is from the spoon? What if he looks in the convex side?

If you sit on the beach and look at the ocean through Polaroid sunglasses, the glasses help to reduce the glare from sunlight reflecting off the water. But if you lie on your side on the beach, there is little reduction in the glare. Explain why there is a difference.

34.15 The thin glass shell shown in Fig. E34.15 has a spherical shape with a radius of curvature of 12cm, and both of its surfaces can act as mirrors. A seed high is placed 15.0cmfrom the center of the mirror along the optic axis, as shown in the figure. (a) Calculate the location and height of the image of this seed. (b) Suppose now that the shell is reversed. Find the location and height of the seed’s image.
