Physics
1 answer:
Maksim231197 [3]3 years ago
3 0
Around 1700, when Mechanics was made for the first time by Sir Isaac Newton, he said about the nature of the light that it resembles thiny particles. Somewhat latter , around 1865, Maxwell discovered that the Electromagnetic waves have the same speed as the speed of light. From this resemblance he deduced that light should be an Electromagnetic wave. Latter than this, at around 1900, when trying to explain some peculiarities of the Photoelectric effect, Eistein postulated that light behaves like thiny particles (the older Newton Theory from 1700).
Today we say that LIGHT HAS A DUAL CHARACTER. It is also a wave and a particle. In some experiments light behaves like an Electromagnetic wave (diffraction, reflection, refraction), in other experiments light behaves like thiny particles (quanta): the Photoelectric effect and the Compton effect.

Among the alkali earth metals, the tendency to react with other substances
padilas [110]
Answer D
In alkali earth metals reacrivity increases from top to bottom (opposite of b)
This is because as you go down, the electron shells increase by 1 shell. The farther away a shell is from the nucleus, the higher its tendency to react.
D is true because the more reactive an alkali metal is, the more vigorous the reaction will be with water.
