Sure. We can do it now. But since the wavelength of sound is in the
neighborhood of 620,000 times longer than the wavelength of light,
in order to focus sound into a beam as narrow as you can focus light,
you need a 'dish' that's 620,000 times bigger than the concave mirror
you could use for light.
The 100-inch Hooker telescope on Mt. Wilson has been used to focus laser
light onto the moon. To focus sound into the same size beam, you need a
dish about 978 miles across, with the souind source at its focus.
Just like so many other examples of technology, the science and the math
are bullet-proof and air-tight, and the only thing we're missing is the $$$ .

Where do images come into focus?

What is a broadfire array?
A broadfire array is a type of antenna configuration designed to provide a wide radiation pattern, allowing for effective signal transmission and reception over a large area. Unlike narrowband antennas, which focus energy in a specific direction, broadfire arrays can cover multiple directions simultaneously, making them ideal for applications such as broadcasting and wireless communications. This configuration often employs multiple elements working together to achieve the desired coverage and performance.

Do electron microscopes focus electron beams to create a magnified image of an object?
yes
Which type of mirror is used in a searchlight?
A parabolic mirror is typically used in a searchlight to efficiently reflect and focus light beams in a particular direction. The parabolic shape helps to concentrate the light into a more powerful and directed beam for increased visibility and range.

What should you do when an oncoming car is using its high beam?
Flash your high beams quickly to remind the other driver to drop the high beams and if that doesn't work try to focus on the right side of the road.

How can I achieve precise focus stacking using a focus rail?
To achieve precise focus stacking using a focus rail, follow these steps: Set up your camera on a stable surface. Attach the focus rail to your camera and adjust the distance between the camera and the subject. Use the focus rail to move the camera in small increments to capture multiple images at different focus points. Use photo editing software to combine the images into a single photo with sharp focus throughout.
What is a collection of authors stories in a single book?
A collection of authors' stories in a single book is typically called an anthology. Anthologies often focus on a specific theme, genre, or time period, bringing together multiple authors to contribute their work to the volume.
How many objects can the human eye focus on at one time?
The human eye can focus on one object at a time, as it has a single point of focus. However, the brain can process multiple objects in the visual field simultaneously, allowing us to perceive a wide scene. This means we can detect and be aware of many objects around us, but sharp focus is limited to one at any given moment.

In your 1997 Dodge 1500 when the lights are changed from low to high beams the dash and gauge lights all go out why?
It could be one of two things: This is a factory setting to focus your attention on the road and not the dash. Possibly the high beams are drawing too much power from the alternator.
