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
Answer: False
The sea floor is also known as the seabed or the ocean floor. It is made of mafic rocks (crystallized matter from silicate magma) deposits and minerals including basalt, gabbro, olivine, serpentine, peridotite, and ore minerals from VMS (Volcanic Massive Sulfide). Rocks do not have a smooth surface, therefore, the seabed is not smooth and level.
Answer:
In its purest form, a market economy answers the three economic questions by allocating resources and goods through markets, where prices are generated. In its purest form, a command economy answers the three economic questions by making allocation decisions centrally by the government. so the answer is A
