When should one use the ray model of light?
a. when diffraction isn't significant
b. when diffration is significant
c. when the wavelength is the same size as the aperture width
d. one can always use the ray model
Homework Answers
In ray model of light we assume rays travel in straight lines and rays get reflected or refracted when strike some surface
In this model we complete ignore the wave nature of light.
Diffraction is a phenomenon which shows wave nature of light.lf it is small or insignificant then we assume that there is no wave nature so we adopt ray model of light ignoring wave model of light
Hence option a) when diffraction isn't significant. .

+ X-Ray Diffraction 25 of 30 > A Review Constants Periodic Table Part A X-ray diffraction can be used to obtain structural information of crystalline compounds. X-ray wavelengths are about the same size as the space between atoms in solids. X-rays aimed at a crystal are diffracted by the atoms in the crystalline lattice. This results in an X-ray diffraction pattern, which can be seen on a detector placed behind the crystal. X-rays with a wavelength of 1.58 A scatter...

2. You have a diffraction grating with 2500 lines/cm. You also have a light source that emits light at 2 different wavelengths, 540 nm and 690 nm, at the same time. The screen for your experiment is 1.2 meters from the diffraction grating. A. What is the line spacing for the grating? B. What is the difference in the angle of the 2nd bright fringe for each wavelength for this grating? C. Which wavelength is closer to the center of...

In an experiment to investigate the diffraction of light by a single slit, a narrow parallel beam of light is passed through a narrow slit before it falls on a screen some distance away. Which ofthe following statements is/are correct? 1. If the slit width is reduced, the total light energy falling on the screen is decreased, but the width of the central diffraction band will be increased. 2.

28. When a narrow beam of white light is normally incident on a diffraction grating, you observe that the light to either side forms a complete spectrum from blue to red. Then you see that the spectrum repeats, but this time you see blue, then green, yellow, and purple, green, etc. The purple seems to be a mixture of red and blue light together. As you work through the problem, you conclude that blue light of wavelength 420 nm has...
