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
Total number of gumballs in the gumball machine =
23 + 52 + 34 + 61 + 30 = 200
% of the gumballs being red = 52/200 * 100
= 52/2
<u> = 26 %</u>
Hence, <u>26% of the gumballs</u> are red in the gumball machine
I’m not 100%, but i’d say A
Cause you ate green beans and fried rice
