The particles that make up the nucleus of an atom are protons and neutrons.
The nucleus of an atom is composed of two main types of subatomic particles: protons and neutrons. Protons have a positive electric charge, while neutrons have no electric charge, making them neutral. These particles are relatively heavy compared to electrons, which orbit the nucleus.
The protons and neutrons are held together tightly in the nucleus by a strong force called the nuclear force or strong nuclear force. This force overcomes the repulsive force between positively charged protons, keeping the nucleus stable.
The number of protons in the nucleus determines the element's identity. For example, if an atom has one proton, it's hydrogen; if it has six protons, it's carbon, and so on. This number is called the atomic number. The sum of protons and neutrons in the nucleus is called the mass number.

Explanation:
Meaning of geosynchronous satellite:
A satellite above Earth placed in a geosynchronous circular orbit, inclined at an angle with the equatorial plane of Earth and orbiting at an orbital period equal to that of earth’s rotational period is termed as a geosynchronous satellite. Geosynchronous orbit is a High Earth orbit at a distance of 42,164 kilometres from the centre of earth such that the gravitational pull from earth is fair enough for the object in orbital motion to match with the speed of earth’s rotational period (24 hrs)
As an observer from ground, a geosynchronous satellite appears to be at a stationary point, at any part of the day; since it's velocity synchronizes with the angular velocity that of earth. A geosynchronous satellite orbiting in an equatorial plane without any inclinations is termed as a geostationary satellite.
B) As the frequency of the wave fluctuates, its energy decreases.
C) As the frequency of the wave increases, its energy also increases.
D) As the frequency of the wave changes, its energy remains constant.
As the frequency of the wave increases, its energy also increases. The correct option is C.
The frequency of an electromagnetic wave is defined as the number of oscillations or cycles per unit of time.
The frequency of the wave, on the other hand, is directly proportional to energy.
The energy of an electromagneticwave is precisely proportional to its frequency, according to the equation E = hf, where E represents energy, h is Planck's constant, and f is the frequency of the wave.
Simply said, higher frequency waves have more energy than lower frequency waves.
This is true over the whole electromagneticspectrum, from radio waves to gamma rays. The energy carried by the wave rises as the frequency of the wave increases.
Thus, the correct option is C.

Photons:
According to quantum mechanics light is not a wave but it posses particle nature and light travel in the form of packets of energy and each packet of energy is known as photon or quanta. These photons can travel in all direction from a source like bulb.
The shape of a bulb is nearly spherical and light or photons emitted in all the direction.
