Página 85 - Connect the object-point, 0, with the image-point, /, making it solid in front of the mirror and dotted behind the mirror. Indicate the direction in which light travels along the lines by arrows, as in Fig. 56. At one of the points of reflection erect a normal, that is, a perpendicular to the mirror, and label the angle between the incident ray and this normal the angle of incidence, and the angle between the reflected ray and the normal the angle of reflection. Distance of object from mirror cm....

Página 99 - These two lenses thus arranged constitute the essential parts of a very crude astronomical telescope. Measure the distance between the lenses and compare this distance with the sum of the focal lengths. To measure the magnifying power of the telescope, fasten on the opposite wall of the room — a strip of white paper with a series of thick black lines drawn across it at regular intervals of about one inch. Be sure...

Página 6 - ... 12 PRINCIPLE OF MOMENTS With four or more spring balances apply parallel forces at various points on a rod so as to produce equilibrium. How does the sum of the forces operating in one direction compare with the sum of the forces operating in the opposite direction? How does the sum of the moments tending to produce clockwise rotation compare with the sum of the moments tending to produce counter-clockwise rotation ? Does this relation of moments depend upon the point selected as the axis of...
