7. A plane mirror and a concave mirror (f = 8.00 cm) are facing each other and are separated by a distance of 16.5 cm. An object is placed between the mirrors and is 8.2 cm from each mirror. Consider the light from the object that reflects first from the plane mirror and then from the concave mirror. What is the distance of the image (d₁) produced by the concave mirror?

= The figure is shown TO SCALE. Each block represents a 1.00 cm square. It shows a ray of light entering a rectangular piece of glass (n₂ 1.50) from air (n₁ = 1.00). Find the position (x,y in cm) where the ray exits the glass. Or, if it does not exit the glass, find the (x,y) position of the second point (the second reflection) where total internal reflection occurs. In either case, be sure to check if total internal reflection occurs. Cheese file to unload Movimuvo filo cine: 20MDY

An Unidentified Flying Object. You and your team spot a strange object hovering over the open ocean in broad daylight. You have nothing to reference in order to estimate its distance, height, or size, but you get the idea to use a concave mirror from a signal light. You disassemble the light, extract the mirror, and point it at the sun. You measure the distance to the sun's image from the center of the mirror to be 3.406 m. You then point the mirror at the object and find that its image forms 3.441 m from the center of the mirror. The angle between the line of sight to the object and the horizontal is 28.5 ° (a) What is the distance between you and the object? (b) What is the height of the object above the ground? (c) If the width of the object's image is 11.8 cm, what is the width of the object? (a) Number 1 (b) Number (c) Number i Units Units Units

A concave mirror (f1 = 6.00 cm) and a convex mirror (f2 = −9.00 cm) are facing each other and are  separated by a distance of 30.0 cm. An object is placed halfway between the mirrors. Consider the light from the object to reflect first from the concave mirror and then from the convex mirror.   a) What is the distance of the first image (di1) that is produced by the concave mirror? b) What is the magnification (m1)?  c) Find the distance of the object for the convex mirror (do2)?  d) What is the distance of the final image (di2) produced by the combination of the two mirrors? e) What is the magnification (m2)?  f) What is the overall magnification (m)?  g) Describe the final image formed by the combination of the two mirrors.
