Is grazing emergence same as critical angle?

Charvi Nayyar 29th Feb, 2020

hello aspirant

When the angle of incidence for a prism is 90 degree then the ray just grazes along the surface of the prism . This is known as grazing incidence and in this case the angle of refraction at the first refracting surface is equal to the critical angle of the material of the prism.

hope this helps

is physical education included in Mark sheet which will increase the total??

TANUJ JAIN 24th Feb, 2020

Hi James,

As per my knowledge for CBSE Board the students will be graded for their physical education based on tests conducted by the school. However, it will be included in the mark sheet, but will not have an impact on the overall assessment of the student.

Hope this helped,

Thank You.
