Question

Name: Lab Section: 1 234567 89 Pre-activity: EM Spectrum and Electronic Transitions 1. In the table below, sketch the following things Sketch an EM wave with a Sketch an EM wave with a Sketch an EM wave with a longer wavelength higher frequency lower energy 2. A human eve responds to light with wavelengths from 380-740 nm (the visible spectrum), while a bee's eye responds to wavelengths from 300-650 nm. Some flowers therefore appear differently to humans as they do to bees, as shown in the sunflower below. sequence Bees cannot see colors with wavelengths higher than 650 nm. What color are bees incapable of seeing, violet or red? a. b. Bees can see EM radiation with a Light with 365 nm With visible light wavelength (A) of 300 nm, while humans cannot. Is an EM wave with a A 300 nm higher or lower in energy than visible light? 3. In an atomic clock, a laser is tuned to match the oscillation of a cesium atom between two electronic energy levels. The frequency of this oscillation is precisely 9,192,631,770 Hz What is the wavelength of the light, and what region of the EM spectrum is it in? (Consult Figure 1.) Region: 159

Answer 1

> EM wave with a longer : wave length > EM ware with a higher frequency an in EM wave with a lower, energy (wow every wavelength) d of propagation of wowe. is the of direction of a direction propagation direction the in all 3 cases! & electric field Be magnetic field. 2.a) Bees Cannot Cannot see see with wordlength colour a higher than 650 mm. to a wavelength Shorfer them that of a violet light has a wavelength Shorfer red light So, s among wolt a red colour, red won't be. visible to bees. b. Ane Visible right has the ware length region. 380-740 nm, Ako as ware length a decreases, svergy (6) 4 the light increases, as. Eohe ha planck's constant Eon speed A ligent in vacuum So, a ligent of ware length 300 nm would be higher in energy them visible light. 3. The frequency of light is 9192634770 Hz Pes or s we have the relation, energy (E) of a light, Echoe hy awarelength of the light. so as anyo ng 1 170 It is in the micro-wave region 3-26 xcom.
