Chapter 5: Q1E (page 1104)

Two plane mirrors intersect at right angles. A laser beam strikes the first of them at a point 11.5 cm from their point of intersection, as shown in Fig. E33.1. For what angle of incidence at the first mirror will this ray strike the midpoint of the second mirror (which is 28.0 cm long) after reflecting from the first mirror?

Short Answer

Expert verified

The angle of incidence is 胃i=39.4o.

Step by step solution

01

(a) Concept of Reflection of light.

The bouncing back of a ray of light when it strikes a smooth polished surface is known as Reflection of Light.

02

(d) Determination of angle of incidence.

In case of reflection, if angle of incidence is and the angle of reflection is胃,then,

胃i=胃r ...(i)

Refer to figure below,

From the figure,

迟补苍蠒=14.0cm11.5cm

So, angle of reflection =90掳-蠒

胃r=39.4掳

Thus, from equation (i), the angle of incidence is,

胃i=39.4掳

People with normal vision cannot focus their eyes underwater if they aren鈥檛 wearing a face mask or goggles and there is water in contact with their eyes (see Discussion Question Q34.23). (a) Why not? (b) With the simplified model of the eye described in Exercise 34.50, what corrective lens (specified by focal length as measured in air) would be needed to enable a person underwater to focus an infinitely distant object? (Be careful鈥攖he focal length of a lens underwater is not the same as in air! See Problem 34.92. Assume that the corrective lens has a refractive index of and that the lens is used in eyeglasses, not goggles, so there is water on both sides of the lens. Assume that the eyeglasses are 2.00cm in front of the eye.)

A spherical mirror is cut in half horizontally. Will an image be formed by the bottom half of the mirror? If so, where will the image be formed?

The VLBA (Very Long Baseline Array) uses a number of individual radio telescopes to make one unit having an equivalent diameter of about 8000 km. When this radio telescope is focusing radio waves of wavelength 2.0 cm, what would have to be the diameter of the mirror of a visible-light telescope focusing the light of wavelength 550 nm so that the visible-light telescope has the same resolution as the radio telescope?

Monochromatic light with wavelength 490 nm passes through a circular aperture, and a diffraction pattern is observed on a screen that is 1.20 m from the aperture. If the distance on the screen between the first and second dark rings is 1.65 mm, what is the diameter of the aperture?

A converging lens with a focal length of 12.0 cmforms a virtual image 8.00 mmtall, 17.0 cmto the right of the lens. Determine the position and size of the object. Is the image erect or inverted? Are the object and image on the same side or opposite sides of the lens? Draw a principal-ray diagram for this situation.
