How do you reflect feedback?
Try to focus on what you have learnt and would do differently next time. Acknowledge to those giving feedback that you have listened and will reflect on what has been said. 3) Know what is appropriate feedback. Feedback should be descriptive and focussed on the task/project.
Why is it important for students to self reflect?
Why is student self reflection important? Research shows that a combination of student self-reflection and peer review is most likely to result in deeper learning. Helping students better understand their own level of achievement is likely to reduce costly and time-consuming appeals and complaints.
What are the two types of refractive index?
Relative refractive index– It is the ratio of speed of light in one medium to the speed of light in another medium • Absolute refractive index– It is the ratio of light in vacuum to the speed of light in another medium.
What is called refractive index?
Refractive Index (Index of Refraction) is a value calculated from the ratio of the speed of light in a vacuum to that in a second medium of greater density. The refractive index variable is most commonly symbolized by the letter n or n’ in descriptive text and mathematical equations.
What are the 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 refractive index example?
The symbol n₂ denotes the absolute Refractive Index. For example, the water refractive index is 1.33, which means the speed of light in water is 1.33 times lesser than the speed of the light in vacuum. Optically denser medium is a medium, which has a higher value of the refractive index.
What is effective refractive index?
The effective refractive index contains information on the phase velocity of light, but not on the group velocity; for the latter, one can similarly define an effective group index in analogy to the group index for plane waves in a homogeneous medium.
How do you find the refractive index of water?
The speed of light is faster in water. The Refractive index of water is 1.3 and the refractive index of glass is 1.5. From the equation n = c/v, we know that the refractive index of a medium is inversely proportional to the velocity of light in that medium. Hence, light travels faster in water.
