a.
Answer the following questions.
What are spherical mirrors?
b. Define lateral inversion.
C. What does the point of incidence mean?
d. What do you mean by focus?
e. State the laws of refraction?
Answers
Explanation:
(b) Lateral inversion is the real or apparent reversal of left and right. For example, the letter b when laterally inverted becomes the letter d (more or less). It is well-known that a plane mirror causes the apparent lateral inversion of objects. ... For example, your right side is directly opposite you in your mirror image.
(c) Point of incidence: The point on the surface where the incident ray strikes the surface is called the point of incidence. Reflected ray: The ray of light that bounces back from the surface of an object is called a reflected ray of light
(d) 1 : to cause to be concentrated focused their attention on the most urgent problems. 2a : to adjust the focus of (the eye, a lens, etc.) focus the telescope. b : to bring into focus The results of that research were focused for classroom presentation. 3 : to bring (something, such as light rays) to a focus : ...
(e) the principle that for a ray, radar pulse, or the like, that is incident on the interface of two media, the ratio of the sine of the angle of incidence to the sine of the angle of refraction is equal to the ratio of the velocity of the ray in the first medium to the velocity in the second medium and the incident ray,
