What is assessment reflection?
Reflection is about students becoming aware of their own thinking processes, and being able to make those transparent to others. It enables assessment of the “why” and “how” of the learning, and what needs to be done as a result. Reflection readily follows on from self or peer assessment. the learning process.
What do you mean by reflection?
Reflection is when light bounces off an object. If the surface is smooth and shiny, like glass, water or polished metal, the light will reflect at the same angle as it hit the surface. This is called specular reflection. Most of the things we see are because light from a source has reflected off it.
What is reflection in class 8?
MSBSHSE Class 8 Science Chapter 16 Textbook Exercise Questions
| Regular reflection of light | Irregular reflection of light |
|---|---|
| It occurs on smooth surfaces such as a plane mirror. | It occurs on rough surfaces such as a black board. |
| The reflected rays are parallel to each other. | The reflected rays are non-parallel to each other. |
What is irregular reflection class 8?
Irregular reflection: It is the diffused reflection from uneven surface such that the light rays are not parallel to each other and do not form an image. For example, reflection of light from the surface of a flowing stream does not form an image.
Where do you find irregular reflection in daily life?
Irregular reflection or diffused reflection takes place when the light rays are incident on a surface like a wall, the wood, a leaf of a tree, a piece of leather, a piece of paper or a piece of wool, which are not smooth or polished, so, the different portions of the surface reflect the incident light rays in different …
What is irregular reflection give one example?
Irregular reflection : when a beam of light falls on rough, unpolished surfaces such as wood, paper etc. the light reflects in different directions. Such a reflection of light from an uneven surface is called the irregular or diffused reflection.
What is irregular reflection short answer?
Irregular reflection is the reflection of light or other waves or particles from a surface such that a ray incident on the surface is scattered at many angles rather than at just one angle as in the case of specular reflection.
What is difference between regular and irregular reflection?
In regular reflection, light reflected from a smooth surface in a definite direction. In irregular reflection, light reflected from a rough surface in all directions and not in a definite direction.
What is irregular and regular reflection?
Regular reflection: It is the reflection from a smooth surface such that the light rays are evenly parallel to each other and an image is formed. Irregular reflection: It is the diffused reflection from uneven surface such that the light rays are not parallel to each other and do not form an image.
What is regular reflection and irregular reflection explain with diagram?
REGULAR REFLECTION – It is the reflection from a regular or plane surface. The rays are parallel after the reflection. IRREGULAR REFLECTION – It is the reflection from a plane surface . The rays are not parallel after reflection.
What do you mean by regular reflection?
: reflection such that the angle of reflection of the light is equal to the angle of incidence and on the opposite side of the normal to the point of incidence.
What is regular and irregular reflection explain with diagram?
Regular reflection occurs when a beam of light falls on a smooth and polished surface and irregular reflection occurs when a beam of light falls on a rough surface. Since the surface is uneven, from different points light rays get reflected in different directions and give rise to irregular reflection.
