A mirror hangs 1.75 m above the floor on a vertical wall. A ray of sunlight, reflected off the mirror, forms a spot on the floor 1.14 m from the wall. Later in the day, the spot has moved to a point 2.50 m from the wall.
(a) What is the change in the angle of elevation of the Sun,
between the two observations?
°
(b) What time of day were these observations made?
morning
afternoon

Ch 25 Q 8 Go.) Problem A small mirror is attached to a vertical wall, and it hangs a distance of 1.86 m above the floor. The mirror is facing due east, and a ray of sunlight strikes the mirror early in the morning and then again later in the morning. The incident and reflected rays lie in a plane that is perpendicular to both the wall and the floor. Early in the morning, the reflected ray strikes the floor...

Problem 25.1.01 A light ray strikes a plane mirror lying flat on a horizontal floor, making an angle of incidence of O; = 64.2º. After reflecting from the mirror, the ray makes a spot on a vertical wall. The wall is a horizontal distance d = 1.08 m from the point of reflection, as shown. How high from the floor is the spot on the wall? (Neglect the thickness of the mirror.)

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 m behind the mirror, as shown in the figure(Figure 1) . If you now place a pencil under the edge of the mirror nearer the wall, tilting it upward by 5.0 ? , how much higher on the wall (?y) is the spot? ?y=_________cm
How high from the floor is the spot on the wall?
A light ray strikes a plane mirror lying flat on a horizontal floor, making an angle of incidence = 61.8°. After reflecting from the mirror, the ray makes a spot on a vertical wall. The wall is a horizontal distance d=1.08 m from the point of reflection, as shown. How high from the floor is the spot on the wall? (Neglect the thickness of the mirror.)

You lay a mirror flat on the floor with one edge against a wall and aim a laser at the mirror. The ray reflects from the mirror and strikes the wall. The plane of the incident and reflected rays is perpendicular to the wall. The ray from the laser strikes the mirror 36.1 cm from the wall, and the reflected ray strikes the wall 34.5 cm above the mirror. Find the angle of incidence of the laser ray on the mirror. theta_i...

A flat circular mirror of radius 0.150 m is lying on the floor. Centered directly above the mirror, at a height of 0.710 m, is a small light source. Calculate the diameter of the bright circular spot formed on the 3.10 m high ceiling by the light reflected from the mirror.

Deep in the physics and astronomy basement storeroom, you find a very large concave spherical mirror from an old telescope. The mirror is 2 m across, and has a radius of curvature of 14.0 m. Because this is just a small piece of such a large sphere, the angle of incidence for on-axis rays will always be below 5°, minimizing spherical aberration You try out the mirror for use as a full-length wall mirror.

A metal marble is launched with a speed of v0 = 30.0m/s at 5.0 ◦ relative to the horizontal, from a height of 1.0 m above ground, and towards a very tall vertical wall, which is 6.0 m away from the launch position. The projectile may first hit the wall, or the ground. Whichever it turns out to be, assume that this is an elastic, specular collision, so that the projectile bounces off. After some time, the projectile will have...
