In a periscope, what is the angle between the two plane mirrors?a)30 d...
Explanation:
Periscope:
A periscope is an optical instrument that uses two plane mirrors positioned at an angle to create a reflection in order to view objects that are not in direct line of sight.
Angle between the two plane mirrors:
The angle between the two plane mirrors in a periscope is important as it determines the field of view and the overall effectiveness of the periscope.
Correct Answer:
The correct angle between the two plane mirrors in a periscope is 45 degrees.
Explanation of the angle:
- An angle of 45 degrees between the two plane mirrors allows for an efficient reflection of light and provides a wider field of view.
- This angle ensures that the light entering one mirror is reflected to the other mirror and then to the observer's eye, enabling the viewer to see objects at a different height or around obstacles.
Importance of the angle:
- The 45-degree angle between the two mirrors ensures that the observer can see clearly without distortion and with a wider range of vision.
- This angle strikes a balance between the field of view and the clarity of the image, making the periscope effective for its intended purpose.
In conclusion, the angle of 45 degrees between the two plane mirrors in a periscope is crucial for providing a clear and wide field of view, allowing users to observe objects that are not in direct line of sight effectively.
