- Assume a convex mirror's focal length (f) is 40 cm.
- the object's distance from the mirror's pole (u) is equal to 20 cm
Given that the object's distance from the mirror is smaller than the focal length's absolute value.
Let v be the distance between the picture and the mirror's pole.
Applying the mirror formula, i.e.
The image is therefore upright and virtual (as the plus sign is obtained) (by the ray diagram we can get it)
Magnification factor = |v/u| = image height/object height
=|13.33/20| <1
The height of the image divided by the object height equals one.
Meaning, the height of the image < the height of the object. The image is therefore reduced.
2 & 7. C. real, inverted, and reduced
- In accordance with the inquiry, the object is positioned on the main axis beyond the concave mirror's center of curvature.
- The diagram shows that the mirror's focus is where paraxial light rays from the object after reflection travel.
- A second ray that was traveling through the center of the curve is now retracing its steps after being reflected.
- Between the mirror's focus and center of curvature, these rays collide to create an actual image.
These are the image characteristics:
- Realistic image
- Image is upside-down
- Image quality suffers
- F and C combine to create an image.
3. B. The image is virtual.
The magnification is larger than one, virtual, and erect are the proper answers. A concave mirror's vertex is another name for the mirror's center. A virtual and upright picture is created when anything is placed between the focus and the mirror's center.
4. B. X = centre of curvature, Y = vertex, Z = focal length
The PRINCIPAL AXIS is X.
A concave mirror's major axis is a hypothetical line that passes through the concave mirror's focus, pole, and center of curvature.
Y is the CURVATURE'S RADIUS.
The radius of the glass sphere from which the concave mirror was cut is known as the radius of curvature.
The focus is on Z.
A point on the principal axis of the mirror known as the focus is where paraxial light rays pass after reflecting off of a concave mirror.
5 & 6. C. They can concentrate the Sun's rays to produce intense heat at a spot.
The only sort of mirror that can capture light rays originating from a wide angle and reflect them into a single focus point is a concave mirror.
