Blue light has a typical frequency of 6.67 x 10 14 1014 hz. what is the wavelength associated with this frequency?

In a system, when potential energy decreases, then entropy also decreases. true false

How are series and parallel circuits simililar? both have multiple paths for electrons to travel. both require resistors in their circuits. both require a switch to complete the circuit. both have at least one path for electrons to travel.

Light traveling in water, nwater = 1.33, strikes a plastic block at an angle of incidence of 51.4°; part of the beam is reflected and part is refracted. if the index of refraction of the plastic is 2.0, what is the angle made by the reflected and refracted beams?
