Answer:
1) 60x; 2) 150x
Explanation:
Total magnification = Power of the Ocular X Power of the objective
Power of Ocular = 15x
Power of Objective = 4x ; 10x
1)Total magnification = 15 X 4 = 60x
2)Total magnification = 15 X 10 = 150x
On the earth surface
Explanation:
The long-wavelength radiation is created on the earth surface when electromagnetic radiation is re-emitted.
- The sun releases radiation in form of short-wave.
- They are usually more energetic and with short wavelength and a high frequency.
- When they interact with materials on the earth, they are radiated back as long-wavelength radiation that usually causes heat.
- Ultraviolet rays and other high energy waves are emitted from the sun because it is a very hot body.
- When these radiations enters the earth, they are re-radiated back as long waves with lower energy.
- Earth is cooler than the sun
- When some of the short waves for example, the ultraviolet rays gets to the surface, it is absorbed and re-radiated back.
- When the short waves are absorbed, they lose some of their their energy to the earth surface.
- The remainder is radiated back as less energetic long waves.
- The hotter a body is, the more energetic the radiation it releases.
