Question

Answer

ANSWER

The reflector on the top of the solar cooker is used to focus the solar energy over the glass surface. The mirror reflects the heat energy in a confined area and increases the net input energy to the solar cooker.

Answer

To increase the heat energy at a point. (focus)

Answer

The reflectors are used on the top of the solar cookers. These reflectors,reflects the solar rays towards the main spot of the solar cooker. ... In this way,the solar energy input in the solar cooker increases a lot and the total efficiency of the solar cooker also increase.

Answer

Option(c) becoz--->>>>

A type of parabolic reflector is used to focus a lot more light into a small area. So if the reflect has an area of 1000sq inches, and it's focused on something that 100sq inch of surface.

Answer

C is the correct answer.... because in solar cooker reflector works to collect a lot of rays from sun and reflect those to a point and it causes increase in heat by which food can be cooked.....So they increase the efficiency of Sunlight.

Answer

Focus energy on glass surface.

Answer

Reflectors (mirror) are used to focus the sun rays along with heat radiation inside the box to achieve high temperature.

Answer

To focus the sun energy inside the solar cooker

Answer

The correct answer is option 'C': increase efficiency.

A solar cooker is a device that uses the energy from the sun to heat and cook food. It works by converting sunlight into heat energy and trapping it inside a confined space. One important component of a solar cooker is a reflector.

Reflector in a Solar Cooker:
A reflector is a surface that is designed to reflect and concentrate sunlight onto a specific area. In the case of a solar cooker, the reflector is used to redirect and focus sunlight onto the cooking pot or container. It is typically made of a shiny material like aluminum or polished metal, which has a high reflectivity.

Increasing Efficiency:
The reflector in a solar cooker plays a crucial role in increasing the efficiency of the device. Here's how:

1. Concentration of Sunlight: The reflector allows sunlight to be concentrated onto the cooking pot or container. By reflecting and redirecting sunlight, the reflector increases the intensity of the solar radiation reaching the cooking area. This concentration of sunlight helps to generate higher temperatures, which in turn speeds up the cooking process.

2. Maximizing Heat Capture: The reflector helps to capture and maximize the amount of sunlight that enters the solar cooker. By reflecting sunlight that would have otherwise been lost, the reflector ensures that a greater proportion of the available solar energy is utilized for heating and cooking.

3. Even Distribution of Heat: The reflector helps to evenly distribute the concentrated sunlight onto the cooking area. By reflecting the sunlight from different angles, the reflector ensures that the cooking pot receives heat from all directions. This promotes even heating and helps to cook the food uniformly.

4. Utilizing Diffuse Sunlight: The reflector is particularly useful in capturing diffuse sunlight, which is sunlight that is scattered by the atmosphere. Diffuse sunlight is less intense than direct sunlight but still carries significant solar energy. The reflector helps to redirect and concentrate this diffuse sunlight onto the cooking area, thereby increasing the efficiency of the solar cooker even on cloudy or hazy days.

In conclusion, the use of a reflector in a solar cooker is to increase efficiency by concentrating sunlight, maximizing heat capture, ensuring even distribution of heat, and utilizing diffuse sunlight. The reflector plays a crucial role in enhancing the performance of the solar cooker and speeding up the cooking process.
