The colors in a rainbow are caused by
a)the interaction of the light reflected from different raindrops.
b)the downward motion of the raindrops.
c)different amounts of absorption for light of different colors by the water in the raindrops.
d)different amounts of refraction for light of different colors by the water in the raindrops.
the correct option is,
d)
different amounts of refraction for light of different colors by the water in the raindrops.
because,
the amout of light will under go refraction, internal reflection
and dispersion

Rainbows are created when sunlight of different wavelengths (colors) is refracted and reflected in raindrops. The angle of elevation θ of a rainbow is always the same. It can be shown that θ = 4β-. 2a, where k sin(β) sin(a) and α 59.4° and k 1.33 is the index of refraction of water. Use the given information to find the angle of elevation θ of a rainbow. Hint: Find sin A]+ (Round your answer to one decimal place.) then use...
Math 20 - Calculus I $4.2 - Extra Credit Applied Project: The Calculus of Rainbows Show your work! Good luck! (40pts) Rainbows are created when raindrops scatter sunlight. They have fascinated mankind since ancient times and have inspired attempts at scientific explanation since the time of Aristotle. In this project we use the ideas of Descartes and Newton to explain the shape, location, and colors of rainbows. 1. The figure shows a ray of sunlight entering a spherical raindrop at...
What is dispersion? A) the reflection of colors off the surface of a bright-colored translucent object, like a jewel B) the separation of light into different colors because of how different colors of light refract differently C) the refraction of light as it passes from air into water D)the separation of colors of light because their waves superpose E) the combination of a spectrum of colored lights into white light
Q1:In Young's double-slit experiment using blue light, the interference patterm consists of ? A) a central white band with molti-colored bands on either side B) a central dark band with alternating bright and dark bands on either side C) a central dark band with multi-colored bands on either side D) a central bright band with altemating dark and bright bands on either side Q2:When sunlight falls on an oily film spread on a water puddle, a spectrum of colors is...
What causes the colors that are seen in a soap bubble? (circle the correct answer) (a) Additives in the soap reflect various colors (b) Chemicals in the soap absorb various colors (c) Light waves reflected from the top and bottom surfaces of the soap film can add up constructively for particular wavelengths (d) Dispersion due to differences in indexes of refraction in the soap (e) The interactions of the light with a thin boundary layer where the soap and the...
The colors on an oil slick are caused by reflection and (explain why) a. Diffraction b. Interference c. Refraction d. Polarization e. Ionization
The colours often visible in soap bubbles arise from ... Select one: a. interference between the light reflected from the inner and outer surfaces of the soap/water film b. refraction of light passing through the soap/water film c. Rayleigh scattering of light passing through the soap/water film d. diffraction of light around the bubble d. The shape of a rainbow could be described as "part of a parabola"
The rainbow of visible colors in the electromagnetic spectrum varies continuously from the longest wavelengths (the reddest colors) to the shortest wavelengths (the deepest violet colors) our eyes can detect. Wavelengths near 655 nm are perceived as red. Those near 515 nm are green and those near 475 nm are blue. Calculate the frequency of light (in Hz) with a wavelength of 655 nm, 515 nm, and 475 nm. 655 nm: 515 nm: 475 nm:
A prism can separate white light into a series of different colors called the _______________ _______________. Light is a form of __________________________________________________________. Specific unique amounts of energy is associated with each ________________________ of light. Make a DETAILED sketch of the Radiant Energy Spectrum.
Light is reflected from a transparent coffee table. When the angle of incidence is 52.2°, the reflected light is completely polarized parallel to the surface of the table top. What is the index of refraction of the material of the table?
