A periscope ( See the Fig.) is useful for viewing objects that cannot be seen directly. It can be used in submarines and when watching golf matches from behind a crowd of people. Suppose the object is a distance p1 from the upper mirror and the centers of the two flat mirrors are separated by a distance h. (a) What is the distance of the final image from the lower mirror? (b) Is the final image real or virtual?(c) Is it upright or inverted? (d) What is its magnification?(e) Does it appear to be left–right reversed? (Explain your work)

Expert Solution

a) The distance of final image to lower mirror is

x=p₁ +h

p₁ is the distance of object from the upper mirror

Formula to calculate distance of final image from the lower mirror and the distance between center of two mirror periscope

b) virtual images

A virtual image is an Image formed when the outgoing rays from an object always diverge. A plane mirror from a vitual image positioned behind the mirror

C) This is upright

When the image distance is positive the image is on the same side of the mirror as the object and it is real and inverted .When the image distance is negative, the image behind the mirror, so the image is virtual and upright

D) The magnification is 1.00

The magnification for virtual and upright image is 1.00

m = height of image / height of object

e) No

It does not appear to be left and right reversed

In optice an image is defined as the collection of focous point of light ray coming from object .A real image is the collection of focous point actually made by converging rays while a virtual image is the collection of focus point made by extension of diverging rays

Newton's Law of Cooling states that the rate at which and objects cools is directly proportional to the difference in temperature between the object an the surrounding medium. if an object cools from 125F to 100F in half an hour when surrounded by air at a temperautre of 75F, find it's temperature at the end of the next half hour. (Hint: we wrote a differenial equation involving a proportional relationship before in lecture)
