Vittorio would like to be able to see the logo on his shirt. Draw the incident and reflected rays showing the light from the logo reflecting off the mirror into his eyes. The rays should meet at the point on the mirror that needs cleaning.

Explanation:

Concepts and reason

The concept used in this question is law of reflection.

Firstly, draw the diagram of the incident and reflecting rays from the mirror between eyes and logo.

Finally, draw the diagram of the incident and reflecting rays from the mirror between eyes and shoes.

Fundamentals

The law of reflection states that the incident ray, the reflected ray, and the normal to the surface of the mirror, all lie in the same plane.

Also, the angle of incidence is equal to the angle of reflection.

(A)  The figure 1 shows the path of light from the logo to the eyes of the person.

The angle made by the rays point O with the normal to the surface of the mirror are equal. The vertical distances of the point O from logo and from O to eyes is same as the angle must be same.

(2)  The figure 1 shows the path of light from the shoelace to the eyes of the person.  The angle made by the rays point O with the normal to the surface of the mirror are equal. The vertical distances of the point O from shoelace and from O to eyes is same as the angle must be same.

Ans: Part A

The ray diagram is as follows:

answer: the metamorphic rocks are formed when they are exposed to high pressure and high temperatures. this happens when one of the earth's plates comes in contact with the other plate by traveling in opposite directions, straight into each other or slipping under one another. the friction that is caused by this activity results in   melting of rocks and when it cools they are known as metamorphic rocks. this process needs a controlled amount of pressure and temperature otherwise it may turn into magma.
