By definition, refractive index is the ratio of the velocity of light in vacuum to the velocity of light in a specified medium. The medium here is the liquid. The speed of light through the liquid also depends on the temperature and pressure. At sea level, the liquid is higher in temperature and pressure. So, the speed is gonna be relatively slower because of the movement of atoms. At high altitude, the liquid is at a lower temperature and pressure. The movements of the molecules are lesser, thus, light can move much faster. So, yes, it would be different. The refractive index would be closer to 1 at high altitude, and greater than 1 at sea level.
Answer:
No
Explanation:
Your answer will be no because Mars has less gravity then Earth does but you would still have the same amount of mass therefor If someone goes to Mars and goes back to Earth they would not weigh the same as they did on earth.Hope it helps you!
Answer:
Explanation:
As we know that the level of intensity is given as
here we know
now the sound is travelling in all possible directions so we have
now for level of sound we have
More, fewer electrons than object is neutral
The number of protons tells you what element an atom is. Just knowing the number of neutrons/mass number does not tell you what element an atom is, since atoms of the same element can have different mass numbers. But all atoms with the same number of protons, are also always of the same element.
Hence, we can identify an atom by the number of protons it has
