A 3.0 cm tall object is placed 4.00 cm in front of a lens. An image is produced that is 6.0 cm and also in front of the lens. A. What is the focal length of the lens? B. What is the magnification of the lens? C. Is the image real or virtual? D. Is the image upside down or right-side up?
A 3.0 cm tall object is placed in front of a convex mirror with a focal length of 5.0 cm. (A) If the object is 7.0 cm in front of the mirror what is the position of the image? (B) What is the height of the image? (C) Is the image real or virtual? (D) Is the image upside down or right-side up?
A light ray incident along vector 2i+4j+ √5k strikes on the x-z plane from medium-I of refractive index 2 and enters into medium-Il of refractive index μ₂. The value of μ₂ for which the ray is just totally reflected from the boundary, is (A) 5/4 (B) 6/5 (C) 3√3/5 (D) 8
A ray of light passes from one medium (n₁) to a second medium (n₂). The angle of incidence is___degrees. The angle of refraction is___degrees. The second medium has a____(higher or lower) index of refraction than the first medium.
An object is placed 15.6 cm from a convex lens. An image is produced at -57.6 cm. What is the focal length (in cm) of the lens? Remember that a negative di means that the image is produced behind the lens you still use the same equation in the same way! Round your answer to the nearest 0.1. Do not add units!
A 8.9 cm tall apple is placed 26.2 cm from a convex lens with a focal length of 15 cm. An image is produced at 52.6 cm. How tall is the image? Remember that an inverted image has a negative hi! Round your answer to the nearest 0.1. Do not add units!
A real image is formed 25.0 cm from a mirror. The image is inverted and is 0.25 times the size of the object. What is the focal length of the mirror? What is the object distance? What type of mirror was used?
Which principle does ray 3 demonstrate? C a) A ray parallel to the principal axis will pass through F. b) A ray that passes through the principal axis will reflect through F. Oc) A ray perpendicular to the principal axis will pass through F. O d) A ray that passes through F will reflect parallel to the principal axis.
The image in this mirror will be V a) upright, larger than the original, and virtual b) upright, smaller than the original, and virtual Oc) inverted, smaller than the original, and virtual d) upright, smaller than the original, and real
Question 1 (Mandatory) (1 point) Magnifying mirrors are usually concave because concave mirrors a) form a virtual image that is in front of the mirror b) form a virtual image that is larger than the actual object c) can form either a virtual or a real image d) form a virtual image that is smaller than the actual object a
