WebThe light passing through the two slits is observed on a distant screen. When the widths of the slits are significantly greater than the wavelength of the light, the rules of geometrical … WebThis was supported by our experiment because red and blue light were the most effective when measuring the rate of photosynthesis compared to green light which was simply reflected by the leaves. For example, our data shows that red had 7 leaves float and blue light had 6 leaves float whereas green only had 5 leaves float.
Web16. jan 2024 · The light that emerges from a simple semiconductor diode of shelf-bought lasers tends to be in the wavelength range of 700-800 nanometers, thereby ranging from orange to red in color. A simple diode produces red laser light (Photo Credit : Edgewater Media/Shutterstock) However, research suggests not red, but green lasers to be the most ... Web2. aug 2013 · In 1801 the scientist Johann Wilhelm Ritter was intrigued by Herschel's discovery of an invisible form of light beyond the red portion of the spectrum, Ritter decided to conduct experiments to determine if invisible light existed beyond the violet end of the spectrum as well.

WebThe light passing through the two slits is observed on a distant screen. When the widths of the slits are significantly greater than the wavelength of the light, the rules of geometrical optics hold—the light casts two shadows, and there are two illuminated regions on …
WebRed is of long wave length so its energ is low,it is not enough to overcome the work function ( W) that binds electron to matter.Remember the equation KE=hf=hc/L -W, where KE ejected electron kinetic energy,hc/L is red light energy,L is its wave length, c the speed of light and h is Planck constant.
