What is used to view distant objects?
telescope
So, the device used to see the distant object is a telescope. So, the correct answer is a telescope.
Which lens is used to see far away?
Telephoto Lenses Are Combinations of Convex and Concave Lenses. Most optical devices make use of not just one lens, but of a combination of convex and concave lenses. For example, combining a single convex lens with a single concave lens enables distant objects to be seen in more detail.
What is the best treatment for myopia?
The standard goal of treating nearsightedness is to improve vision by helping focus light on your retina through the use of corrective lenses or refractive surgery….Refractive surgery
- Laser-assisted in situ keratomileusis (LASIK).
- Laser-assisted subepithelial keratectomy (LASEK).
- Photorefractive keratectomy (PRK).
What are the 2 types of telescopes?
There are two main types of optical telescope – reflectors and refractors. Reflectors use a mirror to collect the light, whilst refractors use a lens. Generally, reflectors are better for deep sky objects whilst refractors are useful for planetary observations.
Which is the tool that extends the senses?
For some scientists, though, that is not enough. They rely on tools that go far beyond what their own senses can take in. Binoculars, which are handheld, are two telescopes side-by-side. Telescopes make distant objects such as planets and stars seem bigger and closer. The optical telescope is the most common type.
How are telescopes used to detect distant objects?
Astronomers use telescopes to detect the faint light from distant objects and to see objects at wavelengths all across the electromagnetic spectrum. To learn more about star’s spectra, check out http://www.colorado.edu/physics/PhysicsInitiative/Physics2000/quantumzone/.
What kind of device do scientists use to record?
Scientists who want to record what they see and hear use many devices. A camcorder is a commonly used tool for recording picture and sound together. This battery-powered machine has a built-in microphone. Some camcorders record onto magnetic tape.
How to see the distance between two objects in Photoshop?
To see the distance of two objects in Photoshop, select one layer, then select the Move tool. Hold Ctrl (Mac: Command) while then hover over the layers to see the Smart Guides that will reveal the distance between the layers.
