Focal Length of a convex lens immersed in water
⦿ Chapter : Lens ⦿ Topic : What is the focal length of a convex lens immersed in water ?
The focal length of a convex lens immersed in water depends on the focal length of the lens in air and the refractive index of the water .
When a convex lens is immersed in water, its focal length is less than when it's in air.
There will be an increase in focal length of the convex lens. This is because the refractive index of glass with respect to water is less than the refractive index of glass with respect to air.

⦿ Chapter : Lens ⦿ Topic : State Lens Maker's Formula .... Basically, this formula relates to the focal length (f) of a lens to the refractive index of the lens and the radii of the curvature of its two surfaces. The focal length of the lens depends upon the refractive index of the material used for making the lens and the radius of curvature. This formula is used by the manufacturers for makin...

⦿ Chapter : Lens ⦿ Topic : Aperture of a lens ......... Aperture of a lens is the effective diameter of its light transmitting area. An f-number is a measure of the light-gathering ability of an optical system such as a camera lens. It is calculated by dividing the system's focal length by the diameter of the entrance pupil ("clear aperture"). The f-number is also known as the focal ratio, f-ra...
Concave Lens & its Diagram ‖ Different Parts of a convex lens : Optical Centre , Centre of Curvature
มุมมอง 37หลายเดือนก่อน
⦿ Chapter : Lens ⦿ Topic : Diagram of a concave lens & its different parts.... Concave Lens is a diverging lens that scatters the incident light after refraction. Concave Lens is thinner in the middle and thicker at the edges. The images formed by a concave lens are virtual and erect. Power of the Concave lens is negative and it is widely used in the correction of myopia.

⦿ Chapter : Lens ⦿ Topic : Diagram of a convex lens & its different parts.... A convex lens is a kind of lens that converges rays of light and stays parallel to the principal axis (converging the incident rays towards the principal axis). Convex Lenses are mostly thin at the lower and upper sides, while thick in the middle if compared with a Concave lens. A Convex Lens has the edges curved outw...
Lens ‖ Classification
มุมมอง 422 หลายเดือนก่อน
⦿ Chapter : Lens ⦿ Topic : Classification of Lens ..... Lenses are classified by the curvature of the two optical surfaces. A lens is biconvex (or double convex, or just convex) if both surfaces are convex. If both surfaces have the same radius of curvature, the lens is equiconvex. A lens with two concave surfaces is biconcave (or just concave). If one of the surfaces is flat, the lens is plano...

⦿ Chapter : Lens ⦿ Topic : Define Lens ..... A lens is a transmissive optical device that focuses or disperses a light beam by means of refraction. A simple lens consists of a single piece of transparent material, while a compound lens consists of several simple lenses (elements), usually arranged along a common axis. Lenses are made from materials such as glass or plastic and are ground, polis...

⦿ Chapter : 2nd Law of thermodynamics ⦿ Topic : Find the expression of efficiency of a Carnot's heat engine ..... A Carnot heat engine is a theoretical heat engine that operates on the Carnot cycle. The basic model for this engine was developed by Nicolas Léonard Sadi Carnot in 1824. The Carnot engine model was graphically expanded by Benoît Paul Émile Clapeyron in 1834 and mathematically explo...

⦿ Chapter : Elasticity ⦿ Topic : What is thermal stress ? Thermal stress is the stress produced by any change in the temperature of the material. Thermal stress is induced in a body when the temperature of the body is raised or lowered and the body is not allowed to expand or contract freely. When the applied force is in the form of temperature the resultant stress is called Thermal stress. It ...

⦿ Chapter : Surface Tension ⦿ Topic : Find the radius of new soap bubble when two soap bubbles coalesce .... As the new bubble is formed under isothermal condition, so Boyle’s law holds good and PV = P1 V1@P2V2 or, 4S/r . (4𝝅/3) r^3 = 4S/r 1 . (4𝝅/3) r 1 ^3 4S/r 2 . (4𝝅/3) r 2 ^3 ∴ r = √ ( r 1 ^ 2 r2 ^ 2 ) This is the radius of new soap bubble when two soap bubbles coalesce .

Greatly Explained ❤❤❤❤❤❤❤
@@aiims891 Thank you for your feedback
Best explanation
Great video exactly what i was looking for
Harajaantal.... What is the meaning of this sir???
Thank you very much sir...
If it is zero outside then why we represent mag.fd. lines outside the solenoid in every diagram😢
we show then becase the exist but teir amount (dentsity) is so small compared to the volume outside that it does not have any major magnetic force or effect. unlike the case of bar magnets who have similar shape of mag. field lines outside but the are more in amount or density (more spread out across the large volume) that they do have some effect or magnetic force.... you can open the diagrams of mag. fields of solinoids and bar magnets to see the diffrence in how spread out the field lines are across the volume outside hope that helps !
Thank you very much sir.
You say about dispersion as slit cannot disperse light.any prism is needed.
Where is derivation??
Bengali sir
Thanx sir
It really helped me, Thank you!
Too much talking and writing was so necessary. In fact, it's very annoying to waste my time on this. Try and summarize most of the things.
thank you
Try to provide in hindi , it is understandable
really helpful
Thanks sir
Thank you so much
Can you please explain to me why you used for P1, P2 and P expression for excess pressure inside the bubble and not P(atmospheric) - 4S/R ? Are these pressures equivalent?
