Why is a mirror an optical device?
A mirror is an optical device because it reflects light, forming an image by reflection. It works on the principle of specular reflection, where light rays are reflected at the same angle as they strike the mirror surface. This reflection process allows mirrors to create virtual images that can be seen by the human eye.
What is difference between lens and mirror with table?
A lens is an optical device that refracts light to form an image, while a mirror is an optical device that reflects light to form an image. A lens uses refraction to bend light rays, while a mirror uses reflection to change the direction of light rays. Both lenses and mirrors can be used to focus light and form images.
Is flash memory is optical?
No, its not an optical storage device.
Is a digital memory card an optical device?
It is not an optical device. C D ROM or DVD are optical devices. Whereas a digital memory card is solid state device.
What is the difference between an optical correct mirror and a rue image mirror?
An optical correct mirror preserves the proportions and angles of the reflected image, making it appear as though looking in a regular mirror. On the other hand, a true image mirror reverses the image, so text appears backwards and objects are flipped horizontally.
Is a Cassette an optical storage device?
magnetic storage device
What is the point on a concave mirror optical axis through which every light ray that travels parallel to the optical axis toward the mirror moves after being reflected?
The focus of a concave mirror is the point on its optical axis where light rays parallel to the axis converge after being reflected.
What is a optical device?
CD-R
Does a curved mirror necessarily have optical power?
Yes but a complex curve will not have a simple or single optical power.
Is a optical character reader a input or output device?
Input device
What is optical equipment?
Optical equipment is any device that uses light to perform its function.
What is a refractomer?
A device to measure optical refraction.
