Answer 1

Answer:

1.i) simple microscope

ii) concave mirror

2. i) 40-1000x

ii) about 1,000,000x

Answer 2

Name the following:

(I)

The kind of microscope that consists ofa single biconvex lens.

→Simple / Dissecting Microscope

ii)

The kind of mirror used for throwing lighton the object in Hooke's microscope.

→Concave mirror

What is the maximum magnification that canusually be achieved by

(i) a compound microscope?

→2000 times.

ii) an electron microscope ?

→200,000 times

Additional information

→A simple microscope is one that uses a single lens for magnification, such as a magnifying glass.

→ The simple microscope has only one level of magnification which is due to the presence of single-lens only and is not adjustable.

→If the inner side of the spherical mirror is reflecting, it is called a concave mirror.

→Concave mirrors can form inverted and real images and also virtual and erect images.

→A compound microscope is a type of microscope that uses two sets of lenses to magnify the image under the microscope.

→The usage of both lenses, compounds or magnifies the image of the object below the objective lens to achieve a resolution of 40x, 100x, 400x, 1000x

→Electron Microscope:Uses visible light to magnify objects.

→Utilises electron beams to magnify tiny objects.

→ Low enlargement of objects than its electron counterpart.

→ An advanced tool for magnification offering high resolution.
