Chapter 27: Q38CQ (page 996)

A bright white light underwater is collimated and directed upon a prism. What range of colors does one see emerging?

Short Answer

Expert verified

The range of colors one sees emerging is in VIBGYOR order.

Step by step solution

01

Definition of prism

A prism is a transparent object, such as glass or plastic, that has at least two flat surfaces that make an acute angle.

02

The range of colors we see emerging upon a prism

As white light goes through a prism due to rarefaction, it is split into seven distinct hues. Each color has a different wavelength, thus they span different distances, which is why they are spliced into seven distinct colors.

VIBGYOR order has seven different colors.

V-VIOLET

I-INDIGO

B-BLUE

G-GREEN

Y-YELLOW

O-ORANGE

R-RED

Therefore, when white light passes through a prism, it is divided into seven different hues due to refraction.

Most popular questions from this chapter

The analysis shown in the figure below also applies to diffraction gratings with lines separated by a distance d. What is the distance between fringes produced by a diffraction grating having 125 lines per centimeter for 600‐nmlight, if the screen is 1.05maway?

The distance between adjacent fringes is△y=xλ/d, assuming the slit separation d is large compared withλ.

At what angle is the fourth-order maximum for the situation in Exercise 27.6? 13.

Under what circumstances is the phase of light changed by reflection? Is the phase related to polarization?

Using the result of the problem above, calculate the distance between fringes for 633nm light falling on double slits separated by 0.0800mm, located 3.00mfrom a screen as in Figure 27.56.

Young’s double slit experiment breaks a single light beam into two sources. Would the same pattern be obtained for two independent sources of light, such as the headlights of a distant car? Explain.
