What do radio waves and microwaves have in common?
2 answers:
Answer: Both are at the side of the spectrum that has the lowest frequency.
Explanation:-
Electromagnetic wave is defined as the wave which is associated with both electrical and magnetic component associated with them. They travel with the speed of light.
Both radio and microwaves are electromagnetic waves which are adjacent to each other in electromagnetic spectrum towards lower frequency and higher wavelength.
The relationship between wavelength and frequency of the wave follows the equation:
where,
= frequency of the wave
c = speed of light
= wavelength of the wave

Explanation:
The change in potential energy of the man is given by:
where
m is the man's mass
g is the gravitational acceleration
is the change in height of the man
In this problem, we have:
is the gain in potential energy
g = 9.8 m/s^2 is the gravitational acceleration
is the change in height
Re-arranging the equation and substituting the numbers, we find the mass:
