To solve the problem, we need to determine the type of mirror used in a solar cooker.
1. Function of Mirrors in Solar Cookers:
In a solar cooker, the mirror is used to reflect sunlight and concentrate it at a focal point to generate heat. This heat is then used for cooking.
2. Type of Mirror Required:
A concave mirror is used in solar cookers because it can focus parallel rays of light (such as sunlight) to a single point (the focal point), allowing concentrated energy for cooking.
Final Answer:
The type of mirror used in a solar cooker is Concave (Option A).

| P | If \(n = 2\) and \(\alpha = 180°\), then all the possible values of \(\theta_0\) will be | I | \(30\degree\) or \(0\degree\) |
| Q | If \(n = √3\) and \(\alpha= 180°\), then all the possible values of \(\theta_0\) will be | II | \(60\degree\) or \(0\degree\) |
| R | If \(n = √3\) and \(\alpha= 180°\), then all the possible values of \(\phi_0\) will be | III | \(45\degree\) or \( 0\degree\) |
| S | If \(n = \sqrt2\) and \(\theta_0 = 45°\), then all the possible values of \(\alpha\) will be | IV | \(150\degree\) |
