That depends on the position and focal length
of the optical elements forming the image.
The image distance (61 cm) is positive since the image is on the same side of the lens as the object. Using the lens formula (1/f = 1/d_o + 1/d_i), where d_o is the object distance (12 cm) and d_i is the image distance, the focal length (f) of the lens is approximately 15 cm.
The minimum length of the mirror needed for the tall man to see his full image would be 6 feet. This is because the mirror needs to be at least the same height as the person in order to capture their full image.
The size of the mirror needs to be at least half the height of the person standing in front of it in order for the person to see their full length image. Therefore, a 3 ft tall vertical plane mirror would be the smallest size in which a 6 ft tall person can see their full length image.
A mirror should be at least half the height of the person using it to see a full vertical image. This allows the person to see themselves from head to toe without any obstruction in the mirror.
An image shot horizontally is commonly known as a landscape orientation. This format is wider than it is tall and is often used for capturing panoramic scenes or subjects that benefit from a wider field of view.

When the object is located at the 2F point, the image will also be located at the 2F point on the other side of the lens. In this case, the image will be inverted (i.e., a right side up object results in an upside-down image). The image dimensions are equal to the object dimensions. A six-foot tall person would have an image that is six feet tall; the absolute value of the magnification is exactly 1. Finally, the image is a real image. Light rays actually converge at the image location. As such, the image of the object could be projected upon a sheet of paper.

The image distance (61 cm) is positive since the image is on the same side of the lens as the object. Using the lens formula (1/f = 1/d_o + 1/d_i), where d_o is the object distance (12 cm) and d_i is the image distance, the focal length (f) of the lens is approximately 15 cm.
The image formed in a plane mirror is virtual, and equal in size to the object. so the size of Nishas image will also be 165cm, equal to her own size
The flat object has more drag (air resistance) than the large object.
[object Object]
A common object that is approximately 1 centimeter tall is a standard paperclip.
Width is how wide the object is and length is how tall the object is.
A building 1,300 tall is considered to be 120 stories tall.
Short is to tall as small is to large. In this analogy, short is the opposite of tall, just as small is the opposite of large. The relationship between short and tall is one of relative size, with short being less tall. Similarly, small is less large in terms of size.
