frequency's unit is Hz which mean cycles per second
given frequency * wavelength = speed of wave
speed of light = 3x10^8 m/s
wavelength = 680nm = 680x10^-9 m
frequency * 680x10^-9 m = 3x10^8 m/s
frequency = 3x10^8 / 680x10^-9
= 4.41x10^14 Hz
= 441x10^12 Hz
= 441 THz
which is the frequency for red light
Running stop signs and lights is an indicator that a driver may be operating their vehicle under the influence of drugs.
<span>An implied warranty of merchantability is an implied warranty on a product for sale that essentially guarantees through implication, that a product will reasonably conform to a buyer's standards and that the product is suitable for sale. In other words, unless the seller of the product explicitly states otherwise by using a phrase such as “as is” or “defective” in describing the product, the buyer has the reasonable right to expect that the item he is buying will conform to his basic expectations and will have no flaws that are not immediately discernible or part of the nature of the item.</span>
