4. Illustrate with a Diagram: - Draw a concave mirror with a principal axis. Mark the pole (P) at the center of the mirror, the focus (F) on the principal axis, and indicate the distance between P and F as the focal length (f).

Connect multiple devices to a network, facilitating data transmission, management, and remote access for monitoring purposes

2. Explain the Principle: - When parallel rays of light strike a concave mirror, they reflect off the surface and converge at the focus. This is a key characteristic of concave mirrors, which makes them useful in applications like telescopes and shaving mirrors.

Explain the meaning of the terms focus and focal length in case of a convex mirror, with the help of , suitable ray diagram.

1. Define Focus: - The focus of a concave mirror is defined as the point on the principal axis where all parallel rays of light converge after reflecting off the mirror. It is denoted by the letter 'F'.

You need highly accurate products to prepare and detect seismic and shock activity. Be prepared with our range of detectors

Need visitor access and communication in hard to reach places - our wi-fi systems eliminate cabling issues while maintaing high quality transmission

A double convex lens (R1=R2=10cm) having focal length equal to the focal length of a concave mirror. The radius of curvature of the concave mirror

Protect cameras from weather, vandalism, and tampering, ensuring reliable operation and longevity in outdoor or harsh environments

3. Define Focal Length: - The focal length (denoted as 'f') is the distance between the pole (the center of the mirror's surface) and the focus. It is a measure of how strongly the mirror converges or diverges light.

Protect residences through various devices like cameras, sensors, and alarms, deterring intruders and providing peace of mind to homeowners

Diagram:F|||P−−−−−−−−−⊢−−−−−−−Pr∈cipalAξs|||//////- In the diagram, 'P' represents the pole of the mirror, 'F' represents the focus, and the distance 'PF' is the focal length.
