The Attempt at a Solution
I see no way of doing this
Nicholas.D said:… why do you get magnification apparent in this particuler case?
Nicholas.D said:The only rays however that would form an image …
Nicholas.D said:2.2/10=x/310 ie I used similar triangles to work out how much of the image of the wall I could see. However, the answers use 300 as the distance from the mirror to the image of the wall and 2.5/10 instead of 2.2/10. (I just rooted the 5 to get the side length of the mirror). Have I made another mistake?
The angle of the mirror plays a crucial role in determining how much of the wall behind you can be seen. If the mirror is positioned at a 90-degree angle, you will be able to see the entire wall behind you. However, as the angle decreases, the amount of wall that can be seen decreases as well.
Yes, the distance between the mirror and the wall can have an impact on how much of the wall can be seen. The closer the mirror is to the wall, the more of the wall will be visible in the reflection. However, if the mirror is too close, it may distort the reflection.
Yes, the type of mirror can make a difference in how much of the wall can be seen. A flat mirror will reflect the entire wall behind you, while a concave or convex mirror may distort the reflection and limit the amount of wall that can be seen.
Yes, the lighting in the room can affect how much of the wall can be seen in the mirror. Brighter lighting can provide a clearer reflection and allow for more of the wall to be visible. On the other hand, dim lighting may make it difficult to see the wall behind you in the mirror.
Other factors that can impact how much of the wall can be seen in the mirror include the size and shape of the mirror, the color and texture of the wall, and any objects or obstructions in the way. Additionally, the height of the person looking in the mirror can also affect their line of sight and the amount of wall they can see behind them.
