Nuclear Fusion
Nuclear fusion is a type of nuclear reaction. In nuclear fusion, two or more than two lighter atomic nuclei combine to form a heavier nucleus. During this process, an enormous amount of energy is released. This energy is called nuclear energy. Nuclear fusion is the energy source of the sun and stars.
Fusion Bomb
A fusion bomb is also known as a thermonuclear bomb or hydrogen bomb which releases a large amount of explosive energy during a nuclear chain reaction when the lighter nuclei in it, combine to form heavier nuclei, and a large amount of radiation is released. It is an uncontrolled, self-sustaining nuclear chain reaction where isotopes of hydrogen combine under very high temperature to form helium. They work on the principle of operation of atomic fusion. The isotopes of Hydrogen are deuterium and tritium, where they combine their masses and have greater mass than the product nuclei, get heated at high temperatures, and releases energy.
How did the si became -10.8?
![EXAMPLE 5.17 An object O0', 9.0 cm high, 27 cm in front of a concave lens of
focal length -18 cm. Determine the position and height of its iamge Il' (a) by
construction and (b) by computation.
SOLUTION (a) Choose the two convenient rays from O shown in Fig. 5.47..
1. A ray OP, parallel to the optical axis, is refracted outward in the direction D
as if it came from the principal focus F.
2. A ray through the optical center of the lens is drawn as a straight line OC.
Then II' is the image of 00'. Images formed by concave or divergent lenses
are virtual, erect, and smaller.
