Question

Можно ли с помощью рассеивающей линзы получить действительное изображение предмета? Не нужно рассказывать какое изображение даёт рассеивающая линза,главное почему мы не можем получить действительное изображение??

Answer 1

Для того,чтобы получить действительное изображение предмета, лучи, испускаемые точкой этого предмета, должны собираться тоже в точку.

Если линза рассеивающая, то лучи, испускаемые точкой этого предмета, рассеваются и в точку не собираются - действительное изображение не получится..

Answer 2

Can a Diverging Lens Produce a Real Image of an Object?

Yes, a diverging lens can produce a real image of an object under certain conditions. However, in the case of a diverging lens, the real image is formed under specific circumstances that are different from those of a converging lens.

Diverging lenses are thinner at the center than at the edges and cause light rays to diverge. When the object is placed at a distance less than the focal length of the diverging lens, the diverging lens produces a virtual image that is upright and smaller than the object. This virtual image is formed on the same side of the lens as the object. When the object is placed beyond the focal length of the diverging lens, the diverging lens produces a real image that is inverted and smaller than the object. This real image is formed on the opposite side of the lens from the object.

Why Can't We Obtain a Real Image Using a Diverging Lens?

The reason we cannot obtain a real image using a diverging lens in most practical scenarios is due to the nature of the diverging lens and the way it interacts with light rays. When light rays pass through a diverging lens, they diverge away from each other. This divergence prevents the formation of a real image in the typical situation where the object is placed in front of the lens.

In the case of a diverging lens, the virtual image formed is the result of the diverging nature of the lens and the way it interacts with the light rays from the object. The virtual image formed by a diverging lens is not a real image that can be projected onto a screen or captured on a surface. Instead, it is an apparent image that cannot be projected or captured in the same way as a real image formed by a converging lens.

In summary, while a diverging lens can produce a real image under specific conditions, in most practical scenarios, the nature of the diverging lens and the way it interacts with light rays prevent the formation of a real image that can be captured or projected onto a surface.
