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
I’d say it’s C:) Since they were perceived as an authoritative figure, people felt as if they HAD to listen to them. His whole experiment was centered around learning people’s obedience to authority. Hope this helped:)
