Investigate means to search for something or look in to something
It is traveling in a straight line and its speed is not changing
The relationship between object distance, image distance, and focal length of a spherical mirror is given by
1/f=1/v+1/u
Where
f= focal length of a spherical mirror (distance between the pole and the principal focus of the mirror)
u= object distance (distance between pole and object)
v= image distance (the distance between pole and image)
Answer:
Angle of reflection = 30°
Explanation:
One of the laws of reflection is that the angle of incidence is equal to the angle of reflection.
The angle at which the light strikes the mirror is called the angle of incidence while the angle at which the light gets reflected back is called angle of reflection.
In this case, the angle of incidence is 30 degrees. So, we can say that the angle of reflection is also equal to 30 degrees.
