Q1. Sunlight enters a room at an angle of 32 above the horizontal and reflects from a small mirror lying flat on the floor. The reflected light forms a spot on a wall that is 2.0 behind the mirror. If you now place a pencil under an edge of the mirror nearer the wall, tilting it upward by 5.0, how much higher on the wall is the spot?
Q2. The diameter of the Sun is 1.39x10^9m. Its distance to the Earth is 1.50x10^11 m. Astronomers are using a refractor telescope to observe it, of that the objective has a diameter of 10.0 cm anf focal length of 1.00 m.
a). Try to discover where the image of the Sun is located after the objective.
b). compute the lateral magnification of the Sun by the objective, according to the object distance and image distance.
c). what's the size of the Sun's image formed by the objective, according to the lateral magnification.
Q3. The Saturn's ring has a diameter of about 2.00x10^5km and the distance between the Earth and the Saturn is 1.40x10^9km. Based on your calculation on resolution power, will the ring be visible in telescope?
