How do you get the volume of a rectangular prism if length is not given?
You cannot calculate it without the length. However, it is possible to get the volume by submerging the prism in water and measuring the volume of the displaced water.
How can a rough value of the focal length of a concave mirror be obtained?
rough focal length of concave mirror
Why is concave lens called a negative lens?
Concave lens is called a negative lens because it has a negative focal length.
Why do images in a concave mirror appear inverted?
If an object's distance from the concave mirror is greater than the mirror's focal length, then the mirror image of it will be inverted. If the distance from the concave mirror is less than the focal length of the mirror, the image will not be inverted. No image will be produced if the distance from the mirror to the object is equal to the mirror's focal length.
What is the focal length of concave mirror to form real image?
