Chapter 5: Q8E (page 1152)

An object is 18cm from the centre of a spherical silvered-glass Christmas tree ornament 6cm in diameter. What are the position and magnification of its image?

Short Answer

Expert verified

The position is1.36cm and the magnification is 0.09.

Step by step solution

01

Calculate the focal length of the mirror

The focal length is half the radius of curvature.

f=‐R2f=‐6/22f=‐1.5cm

02

Calculate the object distance

do=18‐Rdo=18‐3do=15cm

03

Calculate the magnification by finding the image distance

The relation between the object distance and the image distance is1do+1di=1f .

1do+1di=1f1di=1‐1.5‐115di=‐1.36cm

The magnification is

m=‐didom=0.09

So, the position is 1.36cmand the magnification is 0.09.

The explanation given in Section 33.6 for the color of the setting sun should apply equally well to the risingsun, since sunlight travels the same distance through the atmosphere to reach your eyes at either sunrise or sunset. Typically, however, sunsets are redder than sunrises. Why? (Hint:Particles of all kinds in the atmosphere contribute to scattering.)

When a sheet of plastic food wrap is placed between two crossed polarizers, no light is transmitted. When the sheet is stretched in one direction, some light passes through the crossed polarizers. What is happening?

34.18 A transparent liquid fills a cylindrical tank to a depth of 3.60m. There is air above the liquid. You look at normal incidence at a small pebble at the bottom of the tank. The apparent depth of the pebble below the liquid’s surface is 2.45m. What is the refractive index of this liquid?

Explain why the focal length of a plane mirror is infinite, and explain what it means for the focal point to be at infinity.
