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.

Where should the object be placed in order to produce a larger object behind a concave mirror?
The object should be placed beyond the focal point of the concave mirror. This will produce a larger, magnified image located behind the mirror. By positioning the object past the focal point, the reflected rays will converge to form an image that is larger compared to the object.
Is a staircase mirror on a bus concave or convex?
A staircase mirror on a bus is typically concave, as it curves inward to provide a wider field of view for the driver to see passengers behind them on the bus. The concave shape helps to eliminate blind spots and improve visibility for the driver.
How You place a flower 18 feet from a concave mirror. The mirror generates a virtual image of the flower that appears to be behind the mirror. What can you infer about the focal point of the mirror?
Since the image is virtual and appears behind the mirror, the focal point of the concave mirror is also located behind the mirror. This indicates that the focal point is a positive value, based on the mirror's characteristics.
Why concave lens diverging light?
A concave lens is thinner at the center than at the edges, causing light rays passing through it to diverge. This divergence is due to the fact that the concave shape causes the light rays to spread out, making them appear to be coming from a virtual focal point behind the lens.
Do concave lenses have negative focal length?
Yes, concave lenses have negative focal lengths. This is because the focal point for a concave lens is located behind the lens itself, causing light rays to diverge.
What did Scout forget back at the auditorium?
Scout forgets her shoes while at the auditorium. She leaves them behind as she is in a rush to get home.
Why was speaker annoyed in the poem at the theatre the lady behind you?
The speaker was annoyed in the poem "At the Theatre, The Lady Behind You" because the lady behind them kept making noise, talking, and rustling her program, distracting the speaker from enjoying the performance.

What is the best place to attach safety reflectors on a costume?
Reflectors on the back of a costume, as well as on the heels and sides of sneakers, are the best places for reflectors on a costume. A car approaching the person in costume from behind then has more of a chance of seeing that person. For young children who are unaware of road rules, it is imperative to make them visible to all drivers.
Which spherical mirror has a virtual focus-concave or convex?
A concave mirror has a virtual focus. This is because the rays of light that are incident on a concave mirror are reflected and appear to diverge from a point behind the mirror, creating a virtual focus.
When Engineers are designing an auditorium for orchestras what must they do to maximize the loudness of the sound heard by the audience?
hang curtains behind the orchestra

True or false. A concave lens usually produces real images?
False. A concave lens usually produces virtual images. Concave lenses cause light rays to diverge, so the image formed is located behind the lens and cannot be projected onto a screen.
