The human retina has three types of receptor cones, eachsensitive to a different range of wavelengths of visible light,as shown in this figure (the colors are merely to differentiatethe three curves from one another; they do not indicate theactual colors represented by each curve):(a) Estimate the energies of photons with wavelengths at themaximum for each type of cone. (b) The color of the sky is dueto scattering of solar light by the molecules of the atmosphere.Lord Rayleigh was one of the first to study scattering of thiskind. He showed that the amount of scattering for very smallparticles such as molecules is inversely proportional to thefourth power of the wavelength. Estimate the ratio of the scatteringefficiency of light at the wavelength of the maximumfor the “blue” cones, as compared with that for the “green”cones. (c) Explain why the sky appears blue even though allwavelengths of solar light are scattered by the atmosphere
Suppose you conduct direct visible spectrophotometry with red fruit punch as your solution. Which wavelengths of light would you expect to be strongly absorbed? Which wavelengths are not strongly absorbed? Explain.
A typical incandescent lightbulb emits approximately 3 x 1018 visible-light photons per second. Your eye, when it is fully dark adapted, can barely see the light from an incandescent lightbulb 10 km away. How many photons per second are incident at the image point on your retina? The diameter of a dark-adapted pupil is 6 mm.
Name the colors in a color spectrum of visible light from low to high wavelength.
Very short pulses of high-intensity laserbeams are used to repair detached portions of the retina of the eye. Thebrief pulses of energy absorbed by the retina weld the detached portionsback into place. In one such procedure, a laser beam has a wavelengthof 810 nm and delivers 250 mW of power spread over a circularspot 510 mm in diameter. The vitreous humor (the transparent fluid thatfills most of the eye) has an index of refraction of 1.34. If the laser pulses are each 1.50 ms long, how much energy is delivered to the retina with each pulse?
State one effect produced by the scattering of light by the atmosphere?
For dispersion of light through a prism which colour has maximum deviation?
Create a conceptual question out of any of these topics
Many animal species can see ultraviolet light but we, the human beings cannot see this light, why ? give an ultimate explanation
Explain why many molecules that demonstrate significant absorption in the UV/Vis do not also fluoresce.
This is about Beer-Lambert’s Law and UV-vis Spectroscopy: 1) How does a solution interact with light?2) How are absorbance and transmittance related? 3) How do you make an absorbance spectrum?
Suppose you measure the scanning (4x) field of vision diameter with a stage micrometer and it is 2 mm. If high power is 40X, and gives 10X more magnification than scanning power, how big will the diameter of the field of vision be using high power?
