In the figure shown, a concave mirror of focal length 5.0 cm and a convex mirror

Question

In the figure shown, a concave mirror of focal length 5.0 cm and a convex mirror also of focal length 5.0 cm are 30.0 cm apart. An object is 15.0 cm from the concave mirror. Consider that light rays from the object strike the concave mirror first. Let the image formed by the concave mirror be the object for the convex mirror. Determine the location, orientation, nature and magnification of the final image (i.e. formed by convex mirror). In the figure shown, three long and straight parallel wires are in the corners of an isosceles right triangle. Determine the magnitude and direction of the net magnetic force per unit length on I_3 due to I_1 and I_2. A monochromatic light is incident on the Young's double slits 0.80 mm apart. The distance between the slits and the screen is 0.85 mm. The combined effects of diffraction and interference created an alternate pattern of bright and dark fringes on the screen with the two - third order bright fringes formed 0.44 mm apart. Find: a) the wavelength of the light in nanometer, b) the distance of the fifth dark fringe from the center in mm, and c) the distance of the fourth order bright fringe from the center in cm. Superman starts from a point above the earth and flies towards the surface of the earth at 0.80C. Lex Luthor at rest on earth's surface measures that Superman started at an altitude of 6000 km. a) As measured by Lex Luthor, how long does rt take Superman to travel from where he started to the surface of the earth? b) As measured by Superman, how much time does it take him to travel from where he started to the surface of the earth? c) If Lex Luthor sees that Superman is 1.30 m "tall" while flying, how tall is Superman if he Is at rest relative to Lex Luthor? A beam of light in glass strikes the surface of water n = 1.33 at an incident angle of 30 degree. a) If the critical angle between the two media is 61 degree, what is the index of refraction of glass? b) If the ray is reflected and refracted, find the total angle between the reflected and the refracted rays.

Explanation / Answer

1. For concave mirror,

f1 = 5 cm

object distance, p1 = 15 cm

Applying 1/f1 = 1/p1 + 1/q1

1/5 = 1/15 + 1/q1

q1 = 7.5 cm

now this image will work as object for lens.

object distance, p2 = 30 - 7.5 = 22.5 cm

f2 = 5 cm

1/5 = 1/22.5 + 1/q2

q2 = 6.43 cm

m = m1 m2 = (-q1 / p1) (-q2 / p2)

= (7.5 x 6.43 ) / ( 15 x 22.5)

m = 0.14

location: 6.43 cm right to the convex mirror

Orientation: upright

Nature: real image

Magnification: 0.14
