They bounce off just like sun rays when they heat the atmosphere they bounce off reflection
Answer:
the answer is b
Explanation:
because you multiply speed times wavelength
When two waves intersect, they interfere and dan at the crossing point one resulting from well-defined characteristics - the combination of the two-product, but continue unchanged one to the other, each conveying his energy.

(b):
(c):
Explanation:
Given that an electron revolves around the hydrogen atom in a circular orbit of radius r = 0.053 nm = 0.053 m.
Part (a):
According to Coulomb's law, the magnitude of the electrostatic force of interaction between two charged particles of charges and respectively is given by
where,
- = Coulomb's constant =
- = distance of separation between the charges.
For the given system,
The Hydrogen atom consists of a single proton, therefore, the charge on the Hydrogen atom,
The charge on the electron,
These two are separated by the distance,
Thus, the magnitude of the electrostatic force of attraction between the electron and the proton is given by
Part (b):
The gravitational force of attraction between two objects of masses and respectively is given by
where,
- = Universal Gravitational constant =
- = distance of separation between the masses.
For the given system,
The mass of proton,
The mass of the electron,
Distance between the two,
Thus, the magnitude of the gravitational force of attraction between the electron and the proton is given by
The ratio :
