照凹鏡看到的影像是什麼樣的?

請問鏡子中的凹鏡所照的影像是放大的還是縮小的?
我說的鏡子是平常用的鏡子,就像平面鏡之類的。
這問題不需要太多的物理解釋,只需要說當你在照凹鏡時,你看到的自己是被放大了,還是縮小了?

✔ 最佳答案
The image is enlarged, virtual and erect.
When used as a normal mirror, such as that used in bathroom for shaving, is a concave mirror. The image is much magnified.

These concave mirrors have a long focal lengths. Only mirrors with short focal length give diminished images.
