How many ray diagrams does a concave mirror have?
For a concave mirror any of the following four ray diagrams can be used for locating the image formed: a) A ray parallel to the principal axis, after reflection, will pass through the principal focus of a concave mirror.
What are the uses or application of concave and convex mirrors give at least 3 examples for each?
Answer
- concave mirrors[ converging mirror]
- satellite dishes, head lights of a car ,telescopes,shaving mirrors, its used by dentists to get a larger image of the teeth ,electron microscope, magnifying glasses, bomb detectors, flash light mirror of a camera.
- convex mirrors[diverging mirror]
Where do the three rays in ray diagram start?
Explanation: The three rays in a ray diagram start from a single point on the object. The three rays are called the principal rays that are used to determine the location and the size of the image.
What are the 4 rules of concave mirror?
Rules for Obtaining Images Formed by a Concave Mirror
- A ray coming parallel to the principal axis is reflected through the principal focus of the concave mirror.
- The ray of light passing the principal focus becomes parallel to the principal axis after being reflected from the mirror.
What are the three rules of concave lens?
Rules for obtaining images formed by concave lens Rule 1: A ray of light parallel to the principal axis of the concave lens appears to be coming from focus after refraction through the lens. Rule 2: A ray of light passing through the optical centre of the concave lens goes straight after refraction through the lens.
