How is light reflected from plane surfaces?
Light is reflected from plane surfaces in accordance with the law of reflection, which states that the angle of incidence is equal to the angle of reflection. This means that when light hits a plane surface, it bounces off in a predictable manner, maintaining the same angle with respect to the surface normal.
Do all types of mirrors give rise to diffused reflection?
No, not all types of mirrors give rise to diffused reflection. Mirrors with smooth surfaces, such as plane or concave mirrors, produce specular reflection where the light rays are reflected at a consistent angle. Diffused reflection occurs with rough surfaces or materials that scatter light in various directions.
Why you look different in a spoon reflection than a plane mirror?
The surface of a spoon is curved, causing light rays to reflect at varying angles. In a plane mirror, the reflection is flat and therefore does not distort the image's proportions. This curvature in the spoon's reflection can make objects appear wider or narrower than they actually are.
Difference in plane and curved mirrors?
Plane mirrors have a flat reflecting surface, while curved mirrors have a reflecting surface that is curved either inward (concave) or outward (convex). Curved mirrors can focus or diverge light rays depending on their shape, resulting in different optical properties compared to plane mirrors. Additionally, curved mirrors have a focal point and focal length, which plane mirrors do not possess.
If the diagram shows a ray of light reflecting from a plane mirror Which two angles are equal by the law of reflection?
The angle of incidence and the angle of reflection are equal by the law of reflection when a ray of light reflects off a plane mirror.
How many plane surfaces are there in a ball?
None. There is one curved suface but no plane surface.
When a curved surface is tangent to a plane surface?
When the two surfaces touch but do not intersect one another.
Name some 4 shapes with curved faces?
Sphere, ellipsoid, torus, paraboloid, hyperboloid are shapes with only curved surfaces. Hemisphere, quadrant, cone and cylinder are examples of shapes with curved and plane surfaces. There are, of course, many others.
How is light reflected from plane surfaces?

This means that when light hits a plane surface, it bounces off in a predictable manner, maintaining the same angle with respect to the surface normal.
What is the definition of an face in math?
A face is any one of the 2-dimensional plane boundaries or surfaces of a solid object. Sometimes the term is also used for curved surfaces.
Do all types of mirrors give rise to diffused reflection?
No, not all types of mirrors give rise to diffused reflection. Mirrors with smooth surfaces, such as plane or concave mirrors, produce specular reflection where the light rays are reflected at a consistent angle. Diffused reflection occurs with rough surfaces or materials that scatter light in various directions.
What is the name of a 3 faced 3-d shape that is not a cilynder?
A lune or biangle. For example, a segment of an orange, which has two plane surfaces and one curved one.
What is the definition of surface in math?
A surface is a 2-dimensional manifold. Most surfaces are curved, in which for a small "differential" section of a surface, a plane figure is uniquely determined.
How many plane face and curved face in cylinder have?
2 plane faces, 1 curved face
Is a plane a curved surface?
No.
How many plane and curved faces of cylinder?
A cyliner has 2 parallel plane faces and 1 curved face
Can you draw an obtuse triangle with two obtuse angles?
Only on a curved surface like a sphere. You must understand non-euclidean geometry (geometry with no flat surfaces like paper). On a curved plane like a sphere all angles>180 On a flat plane like paper all angles=180 And on a saddle shaped plane like a Pringle all angles<180
