Why did Rutherford conclude that the atom was mostly empty space?
olga nikolaevna [1]
Rutherford came to this conclusion after his Gold-Foil experiment. He found that most of the alpha particales(when released) went straight through the gold foil, of which consisted of atoms. In the middle of the atom theres a small nucleus that has mass and positive charge. Because the nucleus is so small the alpha <span>particles were able to go straight through leading to the conclusion that atoms are mostly empty space. </span>

One of the emission lines that provides the green color in fireworks, which com s from barium salts, has a wavelength of 505nm.
PSYCHO15rus [73]

Explanation:

(a)

The relation between frequency and wavelength is shown below as:

c=frequency\times Wavelength&#10;

c is the speed of light having value 3\times 10^8\ m/s

Given, Wavelength = 505 nm

Also, 1 m = 10^{-9} nm

So,  

Wavelength = 505\times 10^{-9} m

Thus, Frequency is:

Frequency=\frac{c}{Wavelength}

Frequency=\frac{3\times 10^8}{505\times 10^{-9}}\ Hz

Frequency=5.94\times 10^{14}\ Hz

(b)

Also, E=\frac {h\times c}{\lambda}

Where,  

h is Plank's constant having value 6.626\times 10^{-34}\ Js

c is the speed of light having value 3\times 10^8\ m/s

So,

E=\frac{6.626\times 10^{-34}\times 3\times 10^8}{505\times 10^{-9}}\ J

E=\frac{10^{-26}\times \:19.878}{10^{-9}\times \:505}\ J

E=3.94\times 10^{-19}\ J

(c)

Electromagnetic spectrum is range of the frequencies and their respective wavelengths of the various type of the electromagnetic radiation.

In order of the increasing frequency and the photon energy and the decreasing wavelength the spectrum are:  

Red , Orange, Yellow, Green, Blue, Indigo, Violet

Increasing wavelength is the opposite trend. Thus, The longest visible wavelength is red and the shortest is violet.
