A camera of 6 centimeter focal length is used to photograph a distant scene. the distance from the lens to the image is approximately?
چھ سینٹی میٹر فوکل لینتھ کا کیمرہ دور دراز کے منظر کی تصویر کشی کے لیے استعمال کیا جاتا ہے۔ لینس سے تصویر کا فاصلہ تقریباً ہے؟
Answer: 6 cm
Explanation
To find the approximate distance from the lens to the image in a camera with a focal length of 6 centimeters, we can use the lens formula:
1/focal length = 1/object distance + 1/image distance
Given information:
- Focal length = 6 centimeters
In this case, the distant scene is being photographed, so we can assume that the object's distance is very large, approaching infinity.
As a result, we can approximate the lens formula as:
1/focal length ≈ 1/image distance
Simplifying the equation:
1/6 cm ≈ 1/image distance
Cross-multiplying:
image distance ≈ 6 cm
Therefore, the distance from the lens to the image is approximately 6 centimeters.
