How are images formed in pinhole cameras?

Light travels in a straight line, forming inverted images.

Lateral inversion causes left to appear right.

The incident ray and reflection lie in the same plane.

Understanding angles is crucial for reflection experiments.

Light in pinhole cameras forms inverted images due to traveling in straight lines, with an emphasis on the equality of object and image distances.
Understanding lateral inversion is key in comprehending images formed in plane mirrors, as demonstrated through experiments showcasing the laws of reflection, including the incident ray, normal, and reflected ray lying in the same plane, and the angle of incidence being equal to the angle of reflection.

Incident ray and reflection experiment conducted by Akshay Watani resulted in a loss of reflection, similar to Nancy's experiment in the ADM chapter of Hindi. The first law of reflection states that the incident ray, normal, and reflected ray lie in the same plane, with the incident ray being perpendicular to the mirror's surface.
The second law of reflection asserts that the angle of incidence is always equal to the angle of reflection, emphasizing the importance of clarity in understanding the angles involved in reflection experiments. An example provided in the text showcases the calculation of the angle of reflection as 30°.
The text delves into the concept of angles in reflection, highlighting the significance of understanding the angles of incidence and reflection, particularly in experiments involving mirrors.
