A convex mirror has a focal length of magnitude f. An object is placed in front of this mirror at a point 2/3 f from the face of the mirror. The image will appear:

upright and enlarged

upright and reduced

behind the mirror

A rocket is zooming by earth and there is pendulum in rocket. observer a is on earth. observer b on rocket. observer a looks at pendulum and sees period as TA. Observe B sees period as TB. What can ya say about 2 measurements?

TA>TB

TA<TB

TA=TB

Is it possible to see a virtual image?

Yes, rays appear to come from a virtual image can be focused by eye just like those from object.

No , since the rays emanate from virtual image do not in fact emanate from image

Yes, by using additional lens to form a real image before light reaches eye

pls answer all as they easier.

A concave mirror of focal length 15 cm is at x=0. An object is placed at x=20 cm. A convex mirror of focal length 15 cm is at x=50 cm. Consider that light rays from the object strike the concave mirror first. Using the image formed by the concave mirror as the object, determine the location and magnification of the final image (formed by the convex mirror).
