Green light has a wavelength of 500 nm in air. Assume green light is reflected from a mirror with angle of incidence 0°. The incident and reflected waves together constitute a standing wave with what distance from one node to the next node?( )...
By exposing the blood and blood components to light of 500 nm and higher, only the sensitizer that is bound to nucleic acids of the pathogens will be activated, thus destroying the sensitizer-pathogenic nucleic acid complex. Because unbound sensitizer is not activated at this wavelength, damage ...
The completion of the number of waves per second is defined as the frequency of light. Mathematically, it is the inverse of the wavelength of light and does not ever change until the number of photons remains the same. Radio waves have the lowest frequency, whereas gamma rays have the ...
4) Light of wavelength 610 nm is incident on a slit of width 0.20 mm, and a diffraction pattern is produced on a screen that is 1.5 m from the slit. What is the distance of the second dark fringe from the center of the bright fringe? (1 nm = 109 m) A.0.68 cm B.0.92 cm C...
How many photons of green light with a wavelength of 500 nm are necessary to have a total energy of 1.0 \muJ? A light wave has a 660 nm wavelength in air. Its wavelength in a transparent solid is 390 nm. Part A) What is the speed of light i...
英语翻译what is the minimun diameter of the pupil that allows resolution of the two stars using light if wavelength 550nm
The H-alpha spectral line has a wavelength of 656 nm in the laboratory. Light of this wavelength is incident at a diffraction grating. The first order maximum is produced at an angle of 36.0^(° ) .The same spectral line from a receding star is observed with the same diffraction grating...
The MS is designed to consist of sub-wavelength mixed-slot arrays of gold combined with a cathode from a bottom-emitting OLED (B-OLED). We focus on thicknesses of layers, such as metal of MS and dielectric layer, which amplify surface plasmon polariton (SPP). We also consider excitation ...
Visible light, with a wavelength from 400 nanometers (nm) to 780 nm, is critical for driving the photosynthesis process of greenhouse plants, but near-infrared light, with a wavelength from 780 nm to 2,500 nm, has little contributions to plant growth and may cause greenhouse overheating. ...
What is the energy carried by a photon of green light with a wavelength of 520 nm? (Plank's constant = {eq}4.136 \times 10{-15} {/eq} eV/Hz) Photon: Photons are the fundamental particles in the field of quantum mechanics and particle ...
