Optics A diagram of a hyperbolic mirror is shown. The property of a hyperbolic mirror is that if you shine a beam of light from the mirror, the light is reflected toward the focal point. For this mirror, where should you place a view lens to see the converging light? Asymptote: y = Reflected light 2 6,

if you want to set fire to a pile of leaves with a lens, which of these is the best one to use? A. convex lens  B. concave lens

Optics The equation 1-1+1 = f р sometimes called a lens-maker's equation, gives the relationship between the focal length f of a thin lens, the distance p of the object from the lens, and the distance q of its image from the lens. We can think of the eye as an optical system in which the ciliary muscle constantly adjusts the curvature of the cornea-lens system to focus the image on the retina. Assume that the distance from the cornea to the retina is 2.5 cm, as shown in the figure below. Object Image 2.5 cm (a) Find the focal length of the cornea-lens system if an object located 56 cm away is to be focused on the retina. (Round your answer to two decimal places.) cm (b) What is the rate of change of the focal length with respect to the distance of the object when the object is 56 cm away? (Round your answer to five decimal places.) cm/cm

Suppose you have a concave mirror as shown in the image below. If h = 1.84m is the height of an object (really the displacement of the top of the object from the axis) and h' = 4.21m is the height of the image, what is the magnitude of the transverse magnification (in units of meters)? Image Object

In many cars the passenger’s side mirror says: “Objects in the mirror are closer than they appear.”   A) Does this mirror form real or virtual images? B) Is the mirror concave or convex?

A concave mirror has a focal length of 17 cm. The mirror forms an image located 35 cm in front of the mirror. What is the magnification of the mirror? Object Image F

In the figure below, a diverging lens and concave spherical mirror are positioned along an optical axis, with an object half way between the two. The distance between the lens and mirror is d = 23.6 cm. The magnitude of the mirror's radius of curvature is 20.1 cm, and the lens has a focal length of flens = -19.0 cm. Lens Object Mirror (a) Considering only the light that leaves the object and travels first toward the mirror, locate the final image formed by this system. (Give the magnitude of the image distance in cm, and select its location with respect to the lens.) image distance image location -Select--- (b) Is this image real or virtual? O real O virtual (c) Is it upright or inverted? O upright O inverted (d) What is the overall magnification? cm

Rays of light coming from the sun (a very distant object) are near and parallel to the principal axis of a concave mirror. After reflecting from the mirror, where will the rays cross each other at a single point? The rays __________ will not cross each other after reflecting from a concave mirror. will cross at the center of curvature. will cross at the point where the principal axis intersects the mirror. will cross at the focal point. will cross at a point beyond the center of curvature.

HW7 Q4 An object with a height of 40cm is placed 2.4m in front of a convex mirror with a focal length of -0.75m. Determine the approximate location of the image using a ray diagram. Express your answer using two significant figures.   Determine the approximate size of the image using a ray diagram. Express your answer using two significant figures. Is the image upright or inverted?

The two mirrors in the figure below meet at a right angle. The beam of light in the vertical plane P strikes mirror 1 at 0₁ as shown. = 47.8° Light beam Mirror 2 1.25 m Mirror 1 P (a) Determine the distance the reflected light beam travels before striking mirror 2. m (b) In what direction does the light beam travel after being reflected from mirror 2? above the horizontal Need Help?
