Read the following premise and answer if the hypothesis is true.
A magnifying glass (called a hand lens in laboratory contexts) is a convex lens that is used to produce a magnified image of an object. The lens is usually mounted in a frame with a handle (see image). A magnifying glass can be used to focus light, such as to concentrate the sun's radiation to create a hot spot at the focus for fire starting.
Hypothesis: Magnifying lenses do not have to be mounted.. Is the answer "Yes", "No", or "It's impossible to say"? Respond with only the answer and no additional text.
Yes
No.
