ICSE Class 10 Physics Total Internal Reflection

• A ray of light incident normally on a prism of 60 degree angles .Show the path of the light ray till it emerges out of the prism. The critical angle of glass is 42 degree
• why does the refractionn does not happen in total internal reflection
• Can you explain internal refraction in prism? What is the relationship between critical angle and refractive index?
• What colour of the sun is seen when seen from the surface of the moon?  
• Please give the solution
  
• Why in total internal reflection,light ray must pass from denser to rarer medium ONLY?
• Draw a labelled diagram to show a deviation of 90° using a right-angled prism. 
• Why for total internal reflection light must travel from denser to rarer medium? please tell me sir
• Practical file  to verify laws of reflection of light ( complete activity consisting of- aim,appratus,tools,theory experimental setup, procedure, observations,result )
