### Summary Chapter 10 Class 10 Science

• Light seems to travel in straight lines.
• Mirrors and lenses form images of objects. Images can be either real or virtual, depending on the position of the object.
• The reflecting surfaces, of all types, obey the laws of reflection. The refracting surfaces obey the laws of refraction.
• New Cartesian Sign Conventions are followed for spherical mirrors and lenses.
• Mirror formula, (1/v)+(1/u)=1/f, gives the relationship between the object-distance (u), image-distance (v), and focal length (f) of a spherical mirror.
• The focal length of a spherical mirror is equal to half its radius of curvature.
• The magnification produced by a spherical mirror is the ratio of the height of the image to the height of the object.
• A light ray travelling obliquely from a denser medium to a rarer medium bends away from the normal. A light ray bends towards the normal when it travels obliquely from a rarer to a denser medium.
• Light travels in vacuum with an enormous speed of 3×10^8 m/s. The speed of light is different in different media.
• The refractive index of a transparent medium is the ratio of the speed of light in vacuum to that in the medium.
• In case of a rectangular glass slab, the refraction takes place at both air-glass interface and glass-air interface. The emergent ray is parallel to the direction of incident ray.
• Lens formula, (1/v)+(1/u)=1/f, gives the relationship between the object-distance (u), image-distance (v), and the focal length (f) of a spherical lens.
• Power of a lens is the reciprocal of its focal length. The SI unit of power of a lens is dioptre.
