Answer 1

Answer:

• An optical lens is generally made up of two spherical surfaces. If those surfaces are bent outwards, the lens is called a biconvex lens or simply convex lens. These types of lenses can converge a beam of light coming from outside and focus it to a point on the other side.
• A convex mirror or diverging mirror is a curved mirror in which the reflective surface bulges towards the light source. Convex mirrors reflect light outwards, therefore they are not used to focus light. ... The image is smaller than the object, but gets larger as the object approaches the mirror.
• A magnified image is a image which is enlarged by a mirror or lens.
• magnifying glass are round piece of glass, usually with a handle, that is used for making things look bigger than they are.
• Prism is a three-dimensional solid object in which the two ends are identical. It is the combination of the flat faces, identical bases and equal cross-sections. The faces of the prism are parallelograms or rectangles without the bases. ... For example, a pentagonal prism has two pentagonal bases and 5 rectangular faces.
• A real image is the collection of focus points actually made by converging rays, while a virtual image is the collection of focus points made by extensions of diverging rays. ... A real image occurs where rays converge, whereas a virtual image occurs where rays only appear to diverge.
• rear view mirrors are mirrors in which a driver can see the traffic behind.
• side-view mirror, also known as a wing mirror, is a mirror placed on the exterior of motor vehicles for the purposes of helping the driver see areas behind and to the sides of the vehicle, outside the driver's peripheral vision.
• a mirror with a surface that is either concave or convex and forms a portion of a true sphere is called spherical mirror.
• virtual image is an image (such as one seen in a plane mirror) formed of points from which divergent rays (as of light) seem to emanate without actually doing so.
