Emergency flares should be placed approximately 200 to 300 feet behind your vehicle to provide adequate warning to oncoming traffic. This distance helps ensure that drivers have enough time to react and slow down. Additionally, if you're on a highway, you may want to place flares further apart to enhance visibility, especially at night or in low visibility conditions. Always follow local regulations regarding flare usage for specific guidelines.

The bulb is so placed in a torch that it just lies at the focus of the concave reflector. By doing this, we obtain a parallel beam of light, that is, light rays tend to travel infinitely, thus could be used to see objects for a longer distance.
Concave reflectors are placed behind the speaker in an auditorium to help direct sound waves towards the audience. The concave shape helps to focus and amplify the sound, improving overall acoustics in the space. This setup ensures that the audience receives clear and evenly distributed sound throughout the auditorium.
