To use a periscope to look over a wall, you would place the periscope on top of the wall and then look into the eyepiece at the other end. The mirrors inside the periscope will reflect the view from above the wall down to your eye, allowing you to see over the wall without exposing yourself.
You can look over a wall with a periscope because the tube has mirrors what are on a 45 degree angle so the light goes in the top, reflects off the top mirror, then onto the bottom mirror and then into your eyes. Don't forget: Light only travels in straight lines
The basic periscope simply shifts the line of sight, so that you can see around a corner or over a wall. It doesn't necessarily do anything to the image just because it's a periscope. But there's no reason you can't add a telescope or wide-angle viewer to a periscope, or even a zoomer to take you smoothly from a wide-angle to a telephoto, in order to add those functions to the shifted line of sight.
The force needed to push a brick wall over would depend on the weight and stability of the wall. Generally, it would require a significant amount of force, likely beyond what an individual could exert alone. It would be more practical to use machinery or tools to attempt to push over a brick wall.
The wall stays standing because of the counterforce exerted by the ground in the form of friction and compression. This force reacts to the person's push, preventing the wall from tipping over. Additionally, the wall's weight and construction provide stability against the force applied by the individual.
No work is done when pushing on a wall because work is defined as force applied over a distance in the direction of the force. When pushing on a wall, the wall does not move, so there is no displacement in the direction of the force, hence no work is done.

An instrument commonly used to look over walls is a periscope. Periscopes are designed to allow users to see objects that are not directly in their line of sight, typically by using a system of mirrors or lenses to reflect the view. They are often used in submarines and by military personnel. Another example is a telescoping pole with a camera or mirror attached, which can also provide a view over obstacles.

you can put it over but the wall will look a bit fat

To install a dryer periscope vent for proper ventilation and safety in your laundry room, follow these best practices: Measure the space between the dryer and the wall to ensure the periscope vent will fit properly. Use a rigid metal periscope vent to prevent lint buildup and improve airflow. Securely attach the periscope vent to both the dryer and the wall using appropriate fasteners. Make sure the vent is not kinked or crushed to allow for efficient airflow. Regularly clean and inspect the vent to prevent lint buildup and reduce the risk of fire hazards.
Please explain what is a "fines wall"
A periscope consists of a tube with mirrors at both ends. The function of a periscope is to allow a person to see objects that are not in their direct line of sight, such as those above a wall or around a corner, by using the reflections from the mirrors to redirect light.
