2c. Calculate the speed of red light with a wavelength of 650. nm in air as it passes through a water droplet with an index of refraction n = 1.33. If the water droplet is a sphere with a radius of 1.5 mm, how many complete wavelengths of this light fit inside the droplet?
Which of the following is TRUE regarding reflection and refraction? a. Reflection can be explained by the particle nature of light while refraction cannot. b. Refraction can be explained by the wave nature of light while reflection cannot. c. Reflection and refraction can be explained by both the wave and particle nature of light. d. Reflection and refraction can only be explained by the wave nature of light. The perception of color does not correspond to a unique set of wavelengths. The human eye distinguishes several hundreds of colors and shades. The eye has only three separate types of visual signals. So the different signal perceptions of colors are combinations of these three visual signals. Perception of colors depends upon the relative stimulation of the three color sensitive cells in the retina of the eye. What are the requirements for perceiving colors? a. Eye and light b. Eye, object, and light c. Eye, light, and shadow d. Eye, light, and medium
The headlights of a car are 1.5 m apart. Your pupil has a diameter of 5 mm, and the wavelength of the light from the headlights is 600 nm. a. If the car is 50 m away from you, what is the angle between the headlights? b. Can you tell whether the car has two headlights or one? c. What is the maximum distance at which you would still be able to resolve headlights? d. The pupil of your eye changes size depending on how much light it is exposed to. If the diameter of your pupil increased from 5 mm to 7 mm, would your answer in part (c) get larger or smaller?
One well-known image of a prism is the following picture a. Given the pattern of light on the far side of the prism, is the index of refraction inside the prism higher or lower than the index of refraction outside the prism? b. List at least one thing that is wrong with this diagram given what we expect the dependence of n on the wavelength of light to be (and assuming the prism is made of a uniform material). c. List at least one thing that is right with this diagram given what we expect the dependence of n on the wavelength of light to be (and assuming the prism is made of a uniform material).
Please answer the questions about light and color: A. Is mixing colored light the same as mixing colored paint? Explain. B. White light is said to be mixture of all colors. Why did mixing red, green, and blue light result in white?
You are in a room lit only by blue light. A chair in that room looks black to you. (Your eyes see red + green light as yellow; your eyes see red+ blue light as magenta; your eyes see green and blue light as cyan) a. What colors of light is the chair reflecting in the blue room? What colors of light is the chair absorbing in that room? Explain. b. You then move the chair out into the sunlight. What possible colors could the chair be in the sunlight? Explain.
Question 1: X-ray Diffraction x-ray diffraction is a method used to identify different types of materials. While this is usually quite a complex process, however for a simple cubic structure, as seen below, we can find the distance between neighboring atoms. The below image shows the diffraction of x-rays passing through a cubic structure and illustrates a change in distance of 2d sine Light rays in phase ● a /I\ 100 20. b d sin 8 2d sin 0 Atoms in crystal If the wavelength of the x-ray is equal to an integer multiple of this change in distance, we will get constructive interference: mλ = 2d sine X-rays of wavelength 0.103 nm reflects off a crystal and a second-order maximum is recorded at a Bragg angle of 25.5°. (a) What is the spacing between the scattering planes in this crystal? (b) At what angle will the third-order maximum occur?
X rays of wavelength 0.0820 nm are scattered from the atoms of a crystal. The second-order maximum in the Bragg reflection occurs when the angle is 20.5°.
