Answer 2

Answer:

• Convex mirror:

A convex mirror has a positive focal length and forms a virtual, smaller and erect image. The object is placed behind the focal point, therefore the image is formed on the same side as the object. The image is also farther away than the object.

• Concave lens:

A concave lens has a negative focal length and forms a virtual, larger and inverted image. The object is placed beyond the center of curvature, therefore the image is formed on the same side as the object and the image is also farther away than the object.

• Plane mirror:

A plane mirror forms a virtual, same-size and erect image. The image is formed at the same distance behind the mirror as the object is in front of the mirror.

Explanation:

the process  to create the ray diagrams

1.Convex mirror:

• Draw an arrow to represent the object placed 15 cm in front of the mirror.

• Draw the normal line at the point of incidence, which is the point where the object arrow touches the mirror.

• Draw the reflected ray from the object, which will be diverging and will appear to be coming from the focal point behind the mirror.

• Draw the chief ray, which is the ray that passes through the center of curvature of the mirror and reflects back parallel to the principal axis.

• Draw the image arrow where the reflected rays intersect, which will be smaller, virtual and erect.

2.Concave lens:

• Draw an arrow to represent the object placed 15 cm in front of the lens.

• Draw the normal line at the point of incidence, which is the point where the object arrow touches the lens.

• Draw the refracted ray from the object, which will be diverging and will appear to be coming from the virtual focus behind the lens.

• Draw the chief ray, which is the ray that passes through the center of the lens and reflects back parallel to the principal axis.

• Draw the image arrow where the refracted rays intersect, which will be larger, virtual and inverted.

3.Plane mirror:

• Draw an arrow to represent the object placed 15 cm in front of the mirror.

• Draw the normal line at the point of incidence, which is the point where the object arrow touches the mirror.

• Draw the reflected ray from the object, which will be parallel to the normal and will appear to be coming from the image behind the mirror.

• Draw the image arrow where the reflected ray and the normal line intersect, which will be same-size, virtual and erect
