What is the significance of the webcam focal length in determining the quality of images and videos captured by the camera?

The webcam focal length is important in determining the quality of images and videos captured because it affects the field of view and sharpness of the image. A shorter focal length provides a wider field of view but may result in distortion, while a longer focal length allows for closer, more detailed shots but with a narrower field of view. The focal length also impacts the depth of field, which affects the clarity and focus of the image.
