Explain, with a diagram, how 2 plane mirrors could be fixed at a dangerous T-junction so that motorists approaching the junction could see all other traffic?
To solve this problem, we can use two plane mirrors strategically positioned at the dangerous T-junction. These mirrors will allow motorists approaching the junction to have a better view of all other traffic, helping them make safer decisions.
Here's how you can fix the mirrors:
Step 1: Determine the location of the mirrors
Identify the ideal positions to fix the mirrors so that they provide the best view of the traffic. These positions should allow motorists to see the traffic approaching from both directions of the T-junction.
Step 2: Material and size of the mirrors
Choose plane mirrors that are large enough to provide a wide field of view, allowing motorists to see approaching vehicles clearly. The mirrors should be made of reflective glass or other suitable materials, providing a high-quality reflection.
Step 3: Fixing the first mirror
Position the first mirror at an angle of 45 degrees to the road, facing one of the directions of the T-junction. Fix the mirror securely to a pole or a suitable support structure at a height convenient for motorists to see.
Step 4: Fixing the second mirror
Position the second mirror at an angle of 45 degrees to the road, facing the opposite direction of the T-junction. This mirror should be fixed in a way that motorists coming from the opposite direction can clearly see the reflection of the first mirror.
Step 5: Alignment and adjustment
Ensure that both mirrors are aligned properly to provide the maximum field of view. Adjust them if necessary to eliminate any blind spots or distortion in the reflection. Motorists approaching the junction should be able to see the reflection of other vehicles clearly in both mirrors.
Here is a diagram illustrating the setup:
------ | M1 |
| M2 |
------ ------
| T-junction |
The "M1" and "M2" indicate the positions of the first and second mirrors, respectively. The dashed line represents the road approaching the T-junction.
With this setup, motorists approaching the T-junction will be able to see all other traffic by looking into the mirrors and observing the reflections. This will greatly improve their visibility and allow them to make safer decisions while navigating the intersection.
thankyou, plz can u describe how it wuld look like so i can draw it 4rm ur explanation.
Incline them at 45 degrees in opposite directions

The approaching car would be looking from the bottom in this aerial view
(the mirror angles shown are not quite right)
