Can focal length and radius of curvature of a lens be same?
NO it cannot be. Because radius of curvature is given by the expression R = 2 f
The focal point of a lens depends on which two things?
Radius of curvature and refractive index of the material
What is the difference between Radius of curvature and centre of curvature?
the center of curvature is the ORIGIN of the radius of curvature
Formula of radius of curvature of double convex lens?
Radius of curvture = twice the focal length of the double convex lens In symbols R = 2*f or f = R/2 Hope u seek the same
What objective lens is the longest?
The lens with the greatest (positive) curvature. The lens with the highest diopter.
How lens power change with curvature of lens surface?
The lens power increases as the curvature of the lens surface becomes steeper. A lens with a larger radius of curvature will have a lower power, while a lens with a smaller radius of curvature will have a higher power. This relationship is described by the lensmaker's equation, which relates the power of a lens to the refractive index of the lens material and the radii of curvature of its surfaces.
What is radius of curvature?
The radius of the sphere of which a lens surface or curved mirror forms a part is called the radius of curvature.
Can focal length and radius of curvature of a lens be same?
NO it cannot be. Because radius of curvature is given by the expression R = 2 f
Formula for the radius of the curvature of the concave lens?
radius of curvature is double of focal length. therefore, the formula is: 1/f = (n-1)[ 1/R1 - 1/R2 + (n-1)d/nR1R2] here f= focal length n=refractive index R1=radius of curvature of first surface R2=radius of curvature of 2nd surface d=thickness of the lens using this, if you know rest all except one, then you can calculate that.
The focal point of a lens depends on which two things?
Radius of curvature and refractive index of the material
What is the difference between Radius of curvature and centre of curvature?
the center of curvature is the ORIGIN of the radius of curvature
Why should you use a convex lens of large radius of curvature in performing newtons ring experiment?
Radius of rings is directly proportional to the square root of the radius of curvature. Thin lens would have larger radius of curvature and hence the option
What does curvature ratio mean in tubing?
Radius of curvature divided by tube diameter. To get the radius of curvature, imaging the bend in the tube is a segment of a circle, the radius of curvature is the radius of that circle.
Formula of radius of curvature of double convex lens?
Radius of curvture = twice the focal length of the double convex lens In symbols R = 2*f or f = R/2 Hope u seek the same
What is the radius of curvature?
The radius of curvature of a circle, or an arc of a circle is the same as the radius of the circle.For a curve (other than a circle) the radius of curvature at a given point is obtained by finding a circular arc that best fits the curve around that point. The radius of that arc is the radius of curvature for the curve at that point.The radius of curvature for a straight line is infinite.
What is difference between curvature and radius of curvature?
Curvature is a general term to describe a graph. Like, concave or convex. Radius of curvature is more exact. If the curve in a 'small' section is allow to continue with the same curvature it would form a circle. that PRETEND circle would have an exact radius. That is the radius of curvature.
How do you find radius of curvature if focal length is given?
radius of curvature = 2Focal length
