Explanation:
Solar energy will not run out (unless the sun burns out), but the supply of fossil fuels we use is slowly depleting. Burning fossil fuel also releases greenhouse gas into the air, which is bad for the atmosphere.
Answer:
The energy of a hydrogen atom's electron is determined by which principal quantum number n value corresponds to the energy state the electron occupies. where n=1,2,3,... is the quantum number that quantizes the energy levels. That is, they are discrete energy values proportional to 1n2 .
Explanation:
Gamma rays
Explanation:
Every member of the electromagnetic radiation has commensurate amount of energy, wavelength and frequencies.
The electromagnetic waves with the shortest wavelengths and the highest frequencies are the gamma rays.
- Gamma rays also are the most energetic electromagnetic radiation.
- The short wavelength of gamma rays suggests that more waves passes with times.
- It's high frequency shows that a high amount of wave passes through a point at each passing of time.
- These factors combines to give its high energy. Energy of an electromagnetic radiation is a factor of its wavelength and frequency.
- Gamma rays are ionizing radiations which causes ionization of gas molecules.
