Question

what is angle of incidnce



​

Answer 1

Answer:

when a light falls on the object and reflect and we draw a normal then angle between normal and incident ray is known as angle of incident

Answer 2

Answer:

hi dude....

......

In geometric optics, the angle of incidence is the angle between a ray incident on a surface and the line perpendicular to the surface at the point of incidence, called the normal.

..which can also be defined as......,

the angle which an incident line or ray makes with a perpendicular to the surface at the point of incidence.

An example of an angle of incidence is the angle between a light hitting a table and a line perpendicular to the table.

importance of angle of incidence in plane;

1.During Takeoff;

During your takeoff roll, the relative wind is parallel to your runway. The angle of incidence defines your angle of attack until you have enough speed (and tail down force) to lift your nose off. And, the angle of incidence reduces your pitch angle, giving you better visibility during takeoff.

2.During Landing;

During landing, the angle of incidence gives you the same advantage. The angle of incidence reduces the pitch angle you need to achieve a high angle of attack, giving you better visibility at slower speeds
