Solution Answer: E Justification: For Plane Mirrors , the reflected image (a virtual image) and object are along the same line, perpendicular to the reflective surface. The image and object are equidistant from the mirror. If you are 3 m in front of the mirror, your reflected image will be located 3 m behind the mirror. Thus, the distance between you and the image will be 6 m. The reflected image s distance from the mirror is constant, and does not change if the observer moves from left to right.

The light that enters the eye that appears to come from the center image has undergone two reflections, one from each mirror. The third image is created here by the red rays. Light travels from the object to the mirror. It then reflects to the second mirror. Image 3 forms behind this second reflection. An imaginary line exists between the

B) As the crate is being pulled up the incline, the height of the crate above the ground is increasing, therefore increasing its gravitational PE. C) The net work done on the crate IS zero because the box is not accelerating. With no acceleration, there is no net force. With no net force, there is no net work done on the crate.

We shall try to understand in this Chapter the r eflection of light by spherical mirrors and refraction of light and their application in real life situations. 10.1 REFLECTION OF LIGHT A highly polished surface, such as a mirror, reflects most of the light falling on it. Y ou ar e already familiar with the laws of r eflection of light.

In reality, what most often happens is a combination of the three fates. Good mirrors reflect about 90 percent of the incident light and absorb the rest.

We began by aligning the three mirrors of the cell so that the beam of light can travel into the chamber of the device, bounce through the cell 16 times and then exit out the other side. The path length was set to 16 passes and the total path length was calculated using the dimensions of the chamber. Next, a light source, chopper, and
