Because its a vacuum, there's no air resistance, they will fall at same time
Applying gravity acceleration rule g=9.8m/s which is taken as 10m/s sometimes.
Answer:
What part of the light wave is related to the brightness of the light?
Amplitude
The amplitude of a wave tells us about the intensity or brightness of the light relative to other light waves of the same wavelength
The brightness of light is related to intensity or the amount of light an object emits or reflects. Brightness depends on light wave amplitude, the height of light waves. Brightness is also somewhat influenced by wavelength.
