the wave's speed v is related to both the frequency f and the wavelength l :v = l f.
Combining the above expression for velocity with the definition of index of refraction, we find a relationship between the wavelength l = v/f in a medium and the wavelength l 0 = c/f in vacuum:
In the above equation, the frequencies cancel because frequency does not change as light moves from one medium to another.

What determines the focal length of two sides of a lens?
The focal length of a lens is determined by the curvature of its surfaces and the refractive index of the material the lens is made of. A lens with a shorter focal length will have more curved surfaces or a higher refractive index. Conversely, a lens with a longer focal length will have less curved surfaces or a lower refractive index.
The relation between focal length and radius of curvature of spherical mirror is?
The relation between focal length (f), radius of curvature (R), and the focal point of a spherical mirror can be described by the mirror equation: 1/f = 1/R + 1/R'. The focal length is half the radius of curvature, so f = R/2.
What cause lenses to have different focal lengths?
Lenses have different focal lengths due to their varying shapes and materials. A thicker lens will have a shorter focal length, while a thinner lens will have a longer focal length. Additionally, the refractive index of the lens material will affect its focal length.
How does change in the thickness of lens change the focal length of lens?
Increasing the thickness of the lens generally decreases the focal length, while decreasing the thickness increases the focal length. This is due to the way light rays bend and converge or diverge as they pass through different thicknesses of the lens. The relationship between lens thickness and focal length is determined by the lens's refractive index and curvature.
Does the focal length of a spherical mirror change if immersed in water?
No, the focal length of a spherical mirror does not change when immersed in water. The change in medium from air to water affects the refractive index and the speed of light, but it does not affect the focal length of the mirror.
What is the relation between focal length and center of curvature?
The focal length of a concave mirror is about equal to half of its radius of curvature.
What determines the focal length of two sides of a lens?
The focal length of a lens is determined by the curvature of its surfaces and the refractive index of the material the lens is made of. A lens with a shorter focal length will have more curved surfaces or a higher refractive index.

What is relation between focal length and radius of curvature in lenses?
The Center of curvature is 2 times the focal length. By the way this is a physics question.

Why concave lens of large focal length is used to find refractive index of liquid?
physics
Lenses are engineered to have specific focal lengths Besides the curvature of the two sides of a lens what determines the focal length?
Besides the curvature of the lens, the refractive index of the material the lens is made of determines the focal length. The refractive index affects how light rays bend as they pass through the lens, ultimately determining the focal point.
How do you calculate focal length of lens?
The focal length of a lens can be calculated by measuring the distance between the lens and the image plane when an object far away is in focus. This distance is the focal length of the lens. Alternatively, the focal length can be found using the lens maker's formula: 1/f = (n-1) * (1/R1 - 1/R2), where f is the focal length, n is the refractive index of the lens material, and R1 and R2 are the radii of curvature of the two lens surfaces.
Magnifying power of simple microscope can be increased by?
Increasing the focal length of the lens or using a lens with a shorter focal length can increase the magnifying power of a simple microscope. Using a lens with a higher refractive index can also enhance the magnification. Additionally, increasing the distance between the lens and the object being observed can improve the magnification.
