At what angle from horizontal Must we keep the mirror?
According to the laws of reflection, angle of incidence is equal to angle of reflection.
What should be the angle between two plane mirrors?
90 degrees
What will be the angle between the incident ray & reflecting surface when the angle of incidence is 60?
Answer. If a ray of light is falling on a plane mirror and an angle of 60 degree is formed, what will be the angle of reflection? = 90 – 60 = 30 degrees. Since, angle of incidence = angle of reflection = 30 degrees.
How are two mirrors arranged?
When two plane mirrors are placed at right angle to each other, then the incident and reflected rays will always be parallel to each other. Was this answer helpful?
How many images are formed when two plane mirrors are kept at an angle of 45 degree?
7 images
How should the mirrors be arranged such that an infinite?
Answer. Explanation: the mirrors should be placed in front of each other that is parallel to each other so as to form infinite images.
At what angle should the mirror be positioned such that an infinite number of images will be formed or seen?
0-degree angle
What makes letter E suitable for observation under microscope?
The printed lowercase letter “e” is suitable for observation under the microscope because it can still be identified even if only part of it is visible. This is because letter “e” is asymmetrical both vertically and horizontally. You can see clearly how its image is changed under the microscope.
What happens when light reflects off a smooth surface at an angle of incidence other than 90 degrees?
The law of reflection states that when a ray of light reflects off a surface, the angle of incidence is equal to the angle of reflection.
What is the laws of reflection?
The law of reflection states that the angle of reflection equals the angle of incidence—θr = θi. The angles are measured relative to the perpendicular to the surface at the point where the ray strikes the surface.
What is a reflective surface?
A reflective surface is one that can bounce back light — like the reflective sun shade that you put over the windshield of your car. It bounces the sun’s rays away, helping the interior cool.
