Applications Of Reflection Of Light

When a light ray (termed as the incident ray) hits a surface and bounces back (forms a reflected ray), the process of reflection of light has taken place.

Sign Convention for Mirrors

A mirror is made of glass that is coated with a metal amalgam on one side due to which the light ray incident on the surface undergoes reflection and not refraction.

In this example, we will find the position and magnification of an image formed by a spherical mirror. A lamp is placed 10 cmcm in front of a concave spherical mirror that forms an image of the filament on a screen placed 3.0 mm from the mirror. What is the radius of curvature of the mirror? What is the lateral magnification? If the lamp filament is 5.0 mmmm high, how tall is its image? SOLUTION SET UP (Figure 1) shows our diagram. SOLVE Both object distance and image distance are positive; we have ss = 10 cmcm and s's′ = 300 cmcm. To find the radius of curvature, we use the following: 1s+1s′110cm+1300cm==2R, and RR = 19.4 cmcm. The lateral magnification mm is obtained from m=y′/y=−s′/s m=y′y=−150mm5mm=−30. To find the height of the image, we simply multiply the height of the object by the magnification: y′=−30×5.0 m=150m REFLECT The image is inverted (as we know because m = -30 is negative) and is 30 times taller than the object. Notice that the filament is not located at the…
Four ray diagrams are shown below. f1, f2 are the focal points for the lenses respectively as shown from left to right. when both focal points occur at the same point their position is designated as "f1/f2". Identify the TWO ray diagrams that show the correct position for the FINAL image for the two-lens systems shown below.
An object is placed 3.4 m in front of a -1.8-m-focal-length (diverging) lens. Where is the image formed, and is it real or virtual? Inverted or upright? Big or small? Sketch the situation, defining all your variables. Include an accurate ray diagram. Please include the ray diagram.
1.Place your object at a distance equal to the focal length (f) of your diverging lens. Where is your image located? Describe the type of image formed based on size, orientation, and condition and provide a screenshot of your set-up. 2.Place your object at a distance less than the focal length (f) of your diverging lens. Where is your image located? Describe the type of image formed based on size, orientation, and condition and provide a screenshot of your set-up.
in step 1 why is the image distance -4 cm?
If an object is 8 cm away from a converging lens of focal length 2 cm where will the image be? Find the magnification (Draw a ray diagram of how this image is formed to see if your answer is plausible.)
An object is placed 7.7 cm in front of a concave mirror of radius of curvature 10-cm. 1) Calculate the image distance. Follow the sign convention. (Express your answer to two significant figures). 2) Calculate the magnification of the image. (Express your answer to two significant figures). 3) Is the image real or virtual? 4) Is the image upright or inverted?
Suppose you have a concave mirror as shown in the image below. If h = 1.28m is the height of an object (really the displacement of the top of the object from the axis) and h′ = 4.91m is the height of the image, what is the magnitude of the transverse magnification (in units of meters)?
Locate the image by tracing it through ray diagramming and answer three questions for the possible positions: a. Is the image erect or inverted?b. Is the image real or virtual?c. Is it enlarged, diminished, or the same size?
An object is placed 10 m before a convex lens with focal length 5.2 m. Another concave lens is placed 15.6 m behind the first lens with a focal length -7.2m (see the figure below). Note: Make a ray diagram sketch in order to check your numerical answer. At what distance is the first image from the first lens? Answer in units of m. What is the magnification of the first image? At what distance is the second image from the second lens? Answer in units of m. What is the magnification of the final image, when compared to the initial object?
You are imaging a pencil through a thin, converging lens as shown in the image below. If p (the distance from the object to the center of the thin lens) is 8.15m and the focal length of the thin lens is 0.42m, how far away (in meters) from the center of the thin lens is the real image located (the real image will be on the right-side of the lens in this particular example illustrated below)?
You are imaging a pencil through a thin, converging lens as shown in the image below. If p (the distance from the object to the center of the thin lens) is 10m and the focal length of the thin lens is 1.26m, how far away (in meters) from the center of the thin lens is the real image located (the real image will be on the right side of the lens in this particular example illustrated below)?
