How is trignometry used in optics?

Optics deals with refraction - the bending of light rays as they go from a medium of one optical density to another - as in an optical lens. Given the refractive indices of the two materials, the angle of refraction is related to the sine of the angle of incidence.


What is an angle of view?

An angle of view in an agular extent of a given scene as imaged by a camera.


Low angle view?

this term is often confused with angle of field and field of view. The angle of view is the (diagonal) angle subtended by the scene captured in the photograph. This establishes the disc of best definition required for the lens. The angle of field is the angle subtended at the lens rear nodal point by the diagonal of the format itself. In a rectilinear image this is the same as the angle of view, but not for anamorphic images such as those produced by fisheye lenses. 'Field of view' simply describes the area covered in a scene. For example, although the angle of view of a fisheye lens is 180 degrees, its angle of field may be as low as 90 degrees. The field of view may be described as 'horizon to horizon'. For a standard (prime) lens the angle of field is typically 50-55 degrees, the same as the angle of view, and the field of view is roughly the same as that of the eye in a normal viewing of a scene or a picture.

What is different between 1st angle and 3rd angle?

Basically its just where you position the views of the main object, in first angle projection, if you view the object from the left, the view is drawn to the right of the object, in third angle projection, its drawn on the viewing side.
