Answer:
Poynting vector oscillate at a frequency of 2omega
Explanation:
This is because The poynting vector is proportional to the cross product of electric and magnetic field vectors. So Because both fields oscillate sinusoidally with frequency w, trigonometric identities show that their product is a sinusoidal function of frequency of 2w.
There’s no diagram below so no can figure it out

Answer:
Half of the moon or 50%
Explanation:
The first quarter phase of the moon is when the Sun illuminates the half part of the moon while the other half rest in darkness.
In the first quarter phase of the moon, the illumination on the moon surface keeps on rising.
When the new moon appear, there is no illumination while the illumination is 100 % on Full moon.
For the phases of crescent moon, it ranges from 0 - 50% and then for gibbous phase, the range of the illumination is from 50-100%from new
