When an object is placed at the focus of a concave lens, its image is formed on the same side as the object. The image is virtual, erect, and highly diminished, appearing closer to the lens. For more visit here: https://www.tiwariacademy.com/ncert-solutions/class-12/physics/chapter-9/

The refractive index of a transparent medium is the ratio of the speed of light in a vacuum (c) to the speed of light in the medium (v): n = c/v . It indicates optical density. For more visit here: https://www.tiwariacademy.com/ncert-solutions/class-12/physics/chapter-9/

It indicates optical density.
When an object is placed between f (focus) and 2f of a concave mirror: (i) The image formed is real. (ii) The image is magnified and inverted, forming beyond 2f. For more visit here: https://www.tiwariacademy.com/ncert-solutions/class-12/physics/chapter-9/

The velocity of light is minimum in medium A, as it has the smallest angle of refraction (15°), indicating the highest refractive index. Higher refractive index corresponds to lower light velocity in the medium. For more visit here: https://www.tiwariacademy.com/ncert-solutions/class-12/physics/chapRead more

When light passes from a rarer to a denser medium, its wavelength decreases, but the frequency remains unchanged. The speed reduction in the denser medium causes a shorter wavelength while maintaining the same frequency. For more visit here: https://www.tiwariacademy.com/ncert-solutions/class-12/phyRead more

For the same angle of incidence, the angles of refraction in three different media A, B and C are 15°, 25° and 35°, respectively. In which medium will the velocity of light be minimum?
The velocity of light is minimum in medium A, as it has the smallest angle of refraction (15°), indicating the highest refractive index. Higher refractive index corresponds to lower light velocity in the medium. For more visit here: https://www.tiwariacademy.com/ncert-solutions/class-12/physics/chapRead more

Do the frequency and wavelength change when light passes from a rarer to a denser medium?
When light passes from a rarer to a denser medium, its wavelength decreases, but the frequency remains unchanged.
