Given the wavelength of the yellow light (700 nm. in this case) we can find the frequency
<span>by dividing the speed of light c by the wavelength w, that is: f = c/w and we know that </span>
<span>c is equal to 2.998 * 10**8 meters per second. </span>
<span>So the frequency f = (2.998 * 10**8) / (7.0 * 10**-7) = 4.283 * 10**14 cycles per sec. </span>
<span>(or Hz.) Since the threshold frequency of Cs is 9.39 * 10**14 Hz, the red light doesn't </span>
<span>have a high enough frequency (or energy) to cause electron emission. </span>
<span>Hope this answers your question.</span>
C. Model. It's a graphical model that displays one or more weather elements.
Distilled water is touched by man so it would probably be close to 300 degrees farenheit.......maybe.
Answer:
water has several important physical properties. Most of the physical properties of water are quite atypical e.g molar mass is 18.0151grams per mol and melting point is 0.00 degree
Fe because oxidation mean loss of oxygen and Fe lose the oxygen so Fe is oxidised
