Are of green light enters a liquid from air?
The angle 1 is 45∘ and 2 is 30∘. (a) Find the refractive index of liquid. (b) Show in the diagram the path of the ray after it strikes the mirror and re-enters in air.
What are the different types of refractive index?
Some typical refractive indices for yellow light (wavelength equal to 589 nanometres [10−9 metre]) are the following: air, 1.0003; water, 1.333; crown glass, 1.517; dense flint glass, 1.655; and diamond, 2.417. The variation of refractive index with wavelength is the source of chromatic aberration in lenses.
What is a mirror Class 10?
A mirror is defined as reflecting surface and can be explained by the law of reflection, which states that when a ray of light is made to fall on the reflecting surface, the reflected ray has its angle of reflection, incident ray, and the reflected ray are normal to the surface at a point of incidence.
What is mirror in Class 6?
Mirror is an object which reflects light. Shiny and polished surfaces usually act as mirrors. Due to reflection, image of an object is seen in the mirror. Mirror changes the direction of light falling on it.
Which type of mirror is?
Common Types of Mirrors Concave Mirror — Concave mirrors are spherical mirrors that curve inward like a spoon. Convex Mirror — Convex mirrors are also spherical mirrors. However, unlike concave mirrors, they bulge out and distort the reflected image, making it smaller.
What is Mirror example?
Example: Any regular reflecting material which has a polished surface and is not curved in nature is an example of a plane mirror, like household mirrors, looking glass, etc.
What are the three types of mirrors?
Three common types of mirror are the plane mirror, which has a flat, or plane, surface; the convex mirror; and the concave mirror.
Can a mirror be called Metal why why not?
Answer: Mirror is a non metal. Explanation: Glass is an amorphous silica form, so it’s not metal, but you’ll be excited to know it’s either solid or liquid.
What are the two types of curved mirrors?
Curved mirror
- A curved mirror is a mirror with a curved reflecting surface.
- A convex mirror or diverging mirror is a curved mirror in which the reflective surface bulges towards the light source.
- A concave mirror, or converging mirror, has a reflecting surface that is recessed inward (away from the incident light).
Is a mirror that is flat and smooth?
A flat, smooth mirror is called a plane mirror.
What is the mirror equation?
The mirror equation expresses the quantitative relationship between the object distance (do), the image distance (di), and the focal length (f). The magnification equation relates the ratio of the image distance and object distance to the ratio of the image height (hi) and object height (ho).
What is radius of curvature of a mirror?
The radius of curvature of a spherical mirror is the radius of the circle of which the spherical mirror is a part. It can also be defined as the distance between the centre of curvature of the mirror and the pole of the mirror on the principal axis. The radius of curvature is also a measure of how curved the mirror is.
How is U and V related?
if v is the image distance and u is the object distance. It can be also defined as the ratio of the height of the image to the height of the object.
What is M vu?
why magnification of mirror m= -v/u.
