Dual nature of radiation and Matter

142673 An object of mass $1 kg$ has energy content of

1

1000 J

2

9 \times 10^{16} J

3

3 \times 10^{8} J

4

1 J

Explanation:

B Given, mass (m) $= 1 kg$
From Einstein equation
$E = {mc}^{2}$
$E = 1 \times {(3 \times 10^{8})}^{2}$
$E = 9 \times 10^{16} J$

142660 In ruby laser, some of aluminium ions are $({Al}^{3 +})$ replaced by:

1 Copper ions

({Cu}^{3 +})

2 Chromium ions

({Cr}^{3 +})

3 Calcium ions

({Ca}^{3 +})

4 None

Explanation:

B Ruby laser is the first working laser that was invented by T.H. Maima in 1960. It is a three level solid state pulsed laser that uses a synthetic ruby crystal or sapphire $({Al}_{2} O_{3})$ as it gain medium and triply ionized chromium $({Cr}^{+})$ is used as a dopant.
