The forms of energy that can be obtained from the ocean are tidal energy, wave energy, and ocean thermal energy. There are several limitations in order to harness these energies. 1.

The forms of energy that can be obtained from the ocean are tidal energy, wave energy, and ocean thermal energy. There are several limitations in order to harness these energies.
1. Tidal energy depends on the relative positioning of the Earth, moon, and the Sun.
2. High dams are required to be built to convert tidal energy into electricity.
3. Very strong waves are required to obtain electricity from wave energy.
4. To harness ocean thermal energy efficiently, the difference in the temperature of surface water (hot) and the water at depth (cold) must be 20ºC or more.
A concave mirror is used in a solar cooker as it uses heat of the sunlight to cook food. The mirror focuses all the incident sunlight at a point. The temperature at that point increases, thereby cooking and heating the food placed at that point.

The refractive index of diamond is 2.42. This means that the speed of light in diamond will reduce by a factor of 2.42 as compared to its speed in air. In other words, the speed of light in diamond is 1/2.42 times the speed of light in vacuum.

In water light travel faster as compare to kerosene and turpentine because the refractive index of water is lower than that of kerosene and turpentine. The speed of light is inversely proportional to the refractive index.

What is geothermal energy?
Geothermal power plants use heat of the Earth to generate electricity. This heat energy of the Earth is known as geothermal energy.

What kind of mirror – concave, convex or plain – would be best suited for use in a solar cooker? Why?
A concave mirror is used in a solar cooker as it uses heat of the sunlight to cook food. The mirror focuses all the incident sunlight at a point. The temperature at that point increases, thereby cooking and heating the food placed at that point.

You are given kerosene, turpentine and water. In which of these does the light travel fastest? Use the information given in Table 10.3.
In water light travel faster as compare to kerosene and turpentine because the refractive index of water is lower than that of kerosene and turpentine. The speed of light is inversely proportional to the refractive index.
