What determines the characteristics of images seen through a magnifying glass?
The characteristics of images seen through a magnifying glass are determined by the magnification power of the lens, the distance between the lens and the object being viewed, and the focal length of the lens. These factors affect the size, clarity, and distortion of the image.
What are the angles between the light rays and the mirrors in a periscope?
In a periscope, the angles between the light rays and the mirrors are typically 45 degrees. This allows the light to undergo two total internal reflections within the mirrors, resulting in the image being seen in the eyepiece in the same orientation as the object outside.
When the reflection of an object is seen in a concave mirror the image will?
The image seen in a concave mirror can be either real or virtual. A real image is formed when light rays actually converge at a point, while a virtual image is formed when light rays only appear to converge. The characteristics of the image will depend on the distance of the object from the mirror and the mirror's focal length.
When can a virtual image be seen on a screen?
A virtual image can be seen on a screen when the light rays from the object converge to form the image on the screen, even though the image is not actually located at that point.
What is the importance of a periscope?
A periscope allows one to see around obstacles or over barriers without being seen. This device is crucial in submarines for observing above the waterline while remaining submerged, providing valuable information for navigation and surveillance.

How periscope is made?
A Periscope is a type of observation material used during World War I. It is made up of two mirrors in parallel position with an angle of 45 degree placed inside a case. Periscope can also be seen on submarines and other military equipment.

What type of word part is Peri?
"peri-" is a prefix. It appears in words like "periscope", "peristalsis", and "perimeter".
How did the iodine affect the image of the onion cell?
Iodine dyes cells a purple color. This enables things to be seen easier under a microscope.
How did the iodine solution affect the image of the cell?
Iodine dyes cells a purple color. This enables things to be seen easier under a microscope.
When can a virtual image be seen on a screen?
A virtual image can be seen on a screen when the light rays from the object converge to form the image on the screen, even though the image is not actually located at that point.

What happens in a periscope?
A periscope uses mirrors to allow someone to see over obstacles or around corners. Light enters through one end of the periscope, reflects off the mirrors inside, and then exits through the eyepiece, providing a view of the surrounding area without being directly in the line of sight.
