Latest FAQs
A spectroscope uses a prism (or a diffraction grating) to disperse light into its component wavelengths. By analyzing the resulting spectrum, scientists can identify the specific wavelengths of light emitted by a substance, helping to determine its composition.
Yes, dispersion can occur in any transparent medium with varying refractive indices for different wavelengths. Water droplets, for example, cause dispersion, which leads to the formation of rainbows. Diamond, with its high refractive index, also causes significant dispersion.
Different colors of light have different wavelengths and refractive indices. Shorter wavelengths, like violet, have a higher refractive index and bend more, while longer wavelengths, like red, have a lower refractive index and bend less.
The order of colors in the spectrum formed by a glass prism is Violet, Indigo, Blue, Green, Yellow, Orange, and Red (VIBGYOR). Violet light bends the most, and red light bends the least.
Yes, prisms can be used to combine or separate different colors of light. In some optical instruments, prisms are used to merge multiple beams of light with different wavelengths into a single beam or to split light into its component wavelengths.
The refractive index of a prism is a measure of how much the prism slows down and bends light. It depends on the material of the prism and the wavelength of light.
Violet light has a shorter wavelength than red light, and light with shorter wavelengths is refracted more because it travels more slowly through the prism. This causes violet light to deviate more than red light.
Refraction is the bending of light when it passes from one medium to another. Dispersion is the splitting of white light into its constituent colors when it passes through a prism due to different refractive indices for different wavelengths.
Laser surgery, such as LASIK, reshapes the cornea to correct its curvature, allowing light to focus correctly on the retina. This procedure can correct myopia, hypermetropia, and astigmatism, often eliminating the need for glasses or contact lenses.
Yes, astigmatism can occur alongside myopia or hypermetropia. In such cases, glasses or contact lenses can be designed to correct both defects simultaneously.
Spherical lenses (concave and convex) are used to correct simple vision defects like myopia and hypermetropia. Cylindrical lenses are used to correct astigmatism, as they focus light differently along different axes to correct irregularities in the curvature of the cornea or lens.
A virtual image cannot be projected on a screen because the light rays do not actually meet but only appear to diverge from a point behind the mirror. A real image, on the other hand, can be projected on a screen because the light rays actually converge at a point.
Mirrors have a smooth, shiny surface that causes most of the light falling on them to be reflected back according to the laws of reflection.
Lateral inversion is the phenomenon where the left side of an object appears as the right side in its mirror image, and vice versa.
The image formed by a plane mirror is virtual, erect, laterally inverted, and of the same size as the object.
Yes, reflection occurs on all surfaces, but the nature of the reflection (regular or diffuse) depends on the smoothness of the surface.
No, convex mirrors always form virtual, erect, and diminished images, as the reflected rays appear to diverge from a point behind the mirror.
Concave mirrors form real images when the object is placed beyond the focus. The reflected rays actually converge and meet at a point, forming a real image.
The image is virtual, erect, and magnified.
The refractive index of air is almost equal to 1 because the speed of light in air is very close to its speed in a vacuum.
