- It's breakfast time and Mr. H entertains himself once more by watching the daily beetle race across the 37.5-cm length of the Wheaties box top. Angie the beetle typically averages 3.77 mm/s and
Bessie the beetle averages 4.78 mm/s. If Bessie gives Angie a 5.4 cm head start, then which beetle
wins and by what distance?
I

The correct answer is

b. False

It's actually the opposite: only a very small part of the electromagnetic spectrum is visible to human eye.

The electromagnetic spectrum consists of a huge range of wavelengths, spanning from gamma rays (with very short wavelength, at the order of 1 pm) to radio waves (with very long wavelength, at the order of kilometers). The only portion of this spectrum visible to the human eye is the "visible light", which has wavelengths between 400 and 700 nanometers approximately.
