Answer 1

Answer:

The theme of this unit has been that we see an object because light from the object travels to our eyes as we sight along a line at the object. Similarly, we see an image of an object because light from the object reflects off a mirror and travel to our eyes as we sight at the image location of the object. From these two basic premises, we have defined the image location as the location in space where light appears to diverge from. Ray diagrams have been a valuable tool for determining the path taken by light from the object to the mirror to our eyes. In this section of Lesson 3, we will investigate the method for drawing ray diagrams for objects placed at various locations in front of a concave mirror.

To draw these diagrams, we will have to recall the two rules of reflection for concave mirrors:

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

Answer 2

Answer:

When the Object is at Infinity

In this condition, we consider two rays parallel to the principal axis originating from the object. These rays after reflection converge and form an image at F, the principal focus of the mirror, in front of the mirror. The image thus formed is highly diminished, point size, real and inverted

The Object is Placed Beyond C

In this situation we consider two different rays emerging from the object. One parallel to the principal axis and the other directed towards the centre of curvature of the mirror. These rays after reflection from an image between the centre of curvature (C) the focus (F). The image thus formed is diminished, real and inverted.

The Object is Placed at C

Here the two rays emerging from the object are one parallel to the principal axis and other passing through the focus of the mirror. These rays after reflection from an image at point C. the image formed has the same size as that of the object and it is real and inverted.

The Object is Placed Between C and F

Here the two rays considered are one parallel to the principal axis and other passing through the principal focus of the concave mirror. The image is formed beyond C. The image is larger compared to the size of the object and it is real and inverted.

Hope this answer helps you out.
