Question 6 of 19

What property of light does not change as a laser pointer’s beam passes from air into water?

Select one of the following:

Wavelength
Speed
Color
Intensity

Explanation

Question 7 of 19

1

Suppose a single beam of green light(h = 510 nm) is split into equal amplitude components by having the light pass through two narrow slits. The intensity of either component by itself on a viewing screen(measured by covering the other component’s slit) is Io = 25 mW/m2. What is the intensity of both components together if the light from one slit travels 6885 nm further than that from the other slit?

Select one of the following:

0
25 mW/m^2
50
100

Explanation

Question 8 of 19

1

The same setup is used as in the previous question except this time the green laser is swapped out for a red (theta = 650 nm) laser with the same power. What is the intensity of light in the "forward direction"' i.e., for theta= 0, on the viewing screen?

Select one of the following:

0 mW/m^2
25
50
100

Explanation

Question 9 of 19

1

How does the distance of separation between bright dots using the green laser, delta yG compare to the separation using the red laser, delta yR Hint: angles are generally quite small for this application, so sin theta ~ tan theta ~ theta.

Select one of the following:

yG/yR = .78
1
1.27
1.62

Explanation

Question 10 of 19

1

KMAN, the flagship radio station of the K-State Sports network, broadcasts at a frequency of 1350 kHz. What is the wavelength of KMAN's electromagnetic radio wave signal?

Select one of the following:

4.5 mm
4.09 km
222 m
.24 mm

Explanation

Question 11 of 19

1

A piccolo produces high pitch sounds mainly because of?

Select one of the following:

Small size
Higher speed of sound inside piccolo
Wide volume range
Played by smaller people

Explanation

Question 12 of 19

1

The optical analog of a loud piccolo would be?

Select one of the following:

A dim violet laser
A dim red laser
A bright violet laser

Explanation

Question 13 of 19

1

Sound and light waves both exhibit all but one of the behaviors below. Which is the odd one out?

Select one of the following:

Refraction
Polarization
Reflection
Diffraction

Explanation

Question 14 of 19

1

Intensity is proportional to (amplitude)^2, and it decreases with separation from the source as 1/(distance)^2. Which types of waves follow these behaviors?

Select one of the following:

Light and sound
Only sound
Only light
Neither

Explanation

Question 15 of 19

1

Initially unpolarized light passed through three successive high quality Polaroid sheets. Sheets 2 and 3 have axes of polarizations with respect to that of the first polarizer of 45◦ and 90◦, respectively. What fraction of the initial intensity passes through all three sheets?

Select one of the following:

0
1/2
1/4
1/8

Explanation

Question 16 of 19

1

When you view the legendary Peter Nelson as the object shown in picture (A) at a distance from your eyes that is greater than the positive focal length of their converging lenses, the actual real images produced on their retinas is closest to which picture?

Select one of the following:

A
B
C
D

Explanation

Question 18 of 19

1

Fiber optic cables can transmit information at a much higher rate than can be sent over copper wires. The property of light most important for this feature is its?

Select one of the following:

Frequency
Propagation speed
Polarization
Intensity

Explanation

Question 19 of 19

1

The physical phenomenon that enables the fiber optic technology is total internal reflection. This occurs when?

Select one of the following:

Light from a low index of refraction material tries to refract into a higher index material at a small angle of incidence with respect to the optic axis.
Light from a high index of refraction material tries to refract into a lower index material at a small angle of incidence with respect to the optic axis.
Light from a low index of refraction material tries to refract into a higher index material at a large angle of incidence with respect to the optic axis.
