Answer:
Visible Light
wavelength = 4000 - 7000 Angstroms = 400 - 700 milli-microns
1 A unit = 10^-10 m
1 mμ = 10^-9 m
My guess would be about 10 years because stars are hot balls of light that are reflections from years ago so it would most likely take awhile
Sound waves actually travel much faster in water than air, but words and the direction of the noise are distorted.
Answer:
fine the area then devide force by area
Explanation:
10000/(0.5*4)= 5000 pa
A wave transfers energy from the source outward in the
direction of wave motion.
To add, <span>in physics, a </span>wave<span> is an oscillation accompanied by a transfer of
energy that travels through a medium (space or mass). Frequency refers
to the addition of time.</span>
