Answer:
On one end of the electromagnetic spectrum are radio waves, which have wavelengths billions of times longer than those of visible light. On the other end of the spectrum are gamma rays, with wavelengths billions of times smaller than those of visible light.
Explanation:
add me as brainliest if u the answer is helpful
A transfer of charge is actually a gross movement of electrons. Charged objects have a normal or "balanced" state. This state is balanced in a sense of positive charges (protons) and negative charges (electrons). When an object has an excess of deficiency of electrons, it will try to regain its balance by releasing or accepting electrons.
The strength of the gravitational forces between two masses depends on
-- the product of the masses,
-- the distance between their centers of mass.
Answer:
240 m
120 m
Explanation:
d = Path difference = 120 m
For destructive interference
Path difference
The longest wavelength is 240 m
For constructive interference
The longest wavelength is 120 m
