Law of reflection states that both direction of both incoming and outgoing rays of light make the same angle with respect to surface normal.
The incident Ray, the reflected Ray and the normal to the reflection surface at the point of the incidence lie in the same plane.

Answer: Tom drove 60 km/hr fast
Speed = Distance traveled / time taken
Explanation:
Given that:
Distance traveled by Tom = 60 km
Time taken by Tom = 1 hour
Speed = ?
Since speed is obtained by dividing distance traveled by the time taken, hence the formula to use is as follows:
speed = distance / time
Speed = 60 km / 1 hour
Speed = 60 km/hr
Thus, Tom had been driving 60 km/hr fast, using the formula "speed = distance / time"

Answer:
1) When <
(hence
< f ) and they are both in front of the mirror (positive), the image will be larger and inverted
2) When >
(and
< f ) such that they are both positive (in front of the mirror), the image will be smaller and inverted
3) When the image is behind the mirror, for convex mirrors and the object is in front the image will be uptight. The magnification of the image will be the ratio of the image distance to the object distance from the mirror
Explanation:
The position of an object in front of a concave mirror of radius of curvature, R, determines the size and orientation of the image of the object as illustrated in the mirror equation
Where:
f = Focal length of the mirror = R/2
= Image distance from the mirror
= Object distance from the mirror
= Image height
= Object height
is positive for an object placed in front of the mirror and negative for an object placed behind the mirror
is positive for an image formed in front of the mirror and negative for an image formed behind the mirror
m is positive when the orientation of the image and the object is the same
m is negative when the orientation of the image and the object is inverted
f and R are positive in the situation where the center of curvature is located in front of the mirror (concave mirrors) and f and R are negative in the situation where the center of curvature is located behind the mirror (convex mirrors)
∴ When <
(hence
< f ) and they are both in front of the mirror (positive), the image will be larger and inverted
When >
(and
< f ) such that they are both positive (in front of the mirror), the image will be smaller and inverted
When the image is behind the mirror, for convex mirrors and the object is in front the image will be uptight. The magnification of the image will be the ratio of the image distance to the object distance from the mirror.
