Be sure to answer all parts. Re m0:38 The blue color of the sky results from the scattering of sunlight by molecules in the air. The blue light has a frequency of about 7.33 x 10" Hz. Calculate the wavelength (in nm) associated with this radiation, and calculate the energy (in joules) of a single photon associated with this frequency. Enter your answers in scientific notation. (a) Wavelength of the radiation: * 10 nm (b) Energy (in joules) of a...

Absorption and transmission: When a photon of light hits a molecule of gas or a particle in the atmosphere, there are three possibilities: 1) it can be absorbed (the energy is converted to heat), 2) it can be reflected (it continues on but in a different direction), 3) or it can be transmitted. These processes determine our ability to see distant objects (such as the mountains around Los Angeles and Irvine) and the colors in the sky (such as blue...

1. "Ultramarine" is a deep blue-colored pigment that was once produced by grinding lapis lazuli, a blue semi-precious stone, into a powder. For most of antiquity it remained amongst the most rare and coveted dyes, until a synthetic form of ultramarine was made by chemists in 1826. The light that is most strongly absorbed by ultramarine has a wavelength of 679 nm. (a) 5 points Calculate the frequency of light that has a wavelength of 679 nm. The speed of...

1. A certain shade of blue has a frequency of 7.01×1014 Hz. What is the energy of exactly one photon of this light? E = ??? J 2. A dental X‑ray typically affects 195 g of tissue and delivers about 3.95 μJ of energy using X‑rays that have wavelengths of 0.0305 nm. What is the energy in electron volts of a single photon of these X‑rays? I got energy of a photon as: 40.7 x 10 ^3 which is correct but...

Question 3 10 pts Blue and white cause strong signals on different color-perception channels. O do O do not Question 4 20 pts Select all statements that are true about our color vision. Reflected light uses subtractive colors. The smaller objects are, the more difficult it is is to distinguish colors. The more separated color patches are, the easier it is to distinguish their colors. The high level distinction of how we perceive color is additive and subtractive. Question 5...
