focal length – ഫോക്കൽ ലെങ്ത്
Focal length is the distance between the optical center of a lens and the point at which the light rays converge to a single point. It is often used to determine the magnification power of a lens.
Principle focus of a convex mirror – ഒരു കോൺവെക്സ് മിററിന്റെ തത്വ ഫോക്കസ്
The principle focus of a convex mirror is the point at which all the rays that are parallel to the principal axis converge after being reflected from the mirror.
A light pass reflected in convex lens – ഒരു ലൈറ്റ് പാസ് കോൺവെക്സ് ലെൻസിൽ പ്രതിഫലിച്ചപ്പോൾ
When light passes through a convex lens, it is refracted, meaning it is bent towards the center of the lens. The light then reflects off the lens, and is then focused at a single point on the other side of the lens. This is known as the focal point.
principle focus of a concave mirror – ഒരു കോൺകേവ് കണ്ണാടിയുടെ തത്വം ഫോക്കസ്
The principle focus of a concave mirror is the point where all light rays that are parallel to the principal axis of the mirror converge to.
when a light pass through a concave mirror the reflection of light – കോൺകേവ് കണ്ണാടിയിലൂടെ ഒരു പ്രകാശം കടന്നുപോകുമ്പോൾ, പ്രകാശത്തിന്റെ പ്രതിഫലനം
When a light passes through a concave mirror, the light is reflected in a way that converges to a single point, known as the focal point. This type of reflection is called a converging reflection.
focus and focal length of a spherical mirror – ഗോളാകൃതിയിലുള്ള കണ്ണാടിയുടെ ഫോക്കസ്, ഫോക്കൽ ലെങ്ത്
The focus and focal length of a spherical mirror are determined by its curvature. The focal length is equal to half the radius of curvature. The focus is located at the center of the mirror.
when the angle of incidence and angle of reflection are equal in spherical mirror – ഗോളാകൃതിയിലുള്ള കണ്ണാടിയിൽ പതന കോണും പ്രതിഫലന കോണും തുല്യമാകുമ്പോൾ
When the angle of incidence is equal to the angle of reflection in a spherical mirror, it is known as the “normal incidence” condition. This occurs when a light ray is incident on the mirror surface at a 90 degree angle.
The law of reflection of light in plane mirror – പ്ലെയിൻ മിററിൽ പ്രകാശത്തിന്റെ പ്രതിഫലന നിയമം
The law of reflection states that when a ray of light reflects off a surface, the angle of incidence (the angle at which the light strikes the surface) is equal to the angle of reflection (the angle at which the light reflects off the surface). This law applies to all types of light and all …
Pole, principle axis, Reflection in spherical mirror – ഗോളാകൃതിയിലുള്ള കണ്ണാടിയിലെ പോൾ , മുഖ്യ അക്ഷം, പ്രതിഫലനം
what is pole, principle axis, Reflection in spherical mirror ? A pole in a spherical mirror is the point of the surface of the mirror that is farthest away from the center of curvature. It is the point at which the light rays that strike the mirror converge. Principle axis in a spherical mirror is …
Aperture – അപ്പേർച്ചർ
The aperture of a mirror is the diameter of its reflecting surface. It is usually measured in millimeters (mm). A full-aperture mirror is one that has a diameter equal to its focal length. For example, a 100mm-focal-length mirror would have an aperture of 100mm.
