2 m
3 m
4 m
What does your eye adjust to produce sharp images of objects arranged at many different distances in front of it?

What property of light does not change as a laser pointer’s beam passes from air into water?
Wavelength
Speed
Color
Intensity
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?
0
25 mW/m^2
50
100
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?
0 mW/m^2
25
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.
yG/yR = .78

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?

222 m
.24 mm
A piccolo produces high pitch sounds mainly because of?

Sound and light waves both exhibit all but one of the behaviors below. Which is the odd one out?
Refraction
Polarization
Reflection
Diffraction
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?
Light and sound

Neither
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?
1/2
1/4
1/8
Similar to the previous question, initially unpolarized light passed through three successive high quality Polaroid sheets. This time the order of sheets 2 and 3 is flipped; and they have axes of polarizations with respect to that of the first polarizer of 90◦ and 45◦, respectively. What fraction of the initial intensity passes through all three sheets?
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?
A

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