Define respiration and explain the experiment to demonstrate aerobic transpiration with well-labeled diagrams.
Define Fraunhofer diffraction. How is transmission grating constructed? Describe necessary theory of diffraction grating.
The beam of light after the reflection at a plane mirror, rotating 2000 times per minute, passes to a distant reflector. it returns to the rotating mirror from which it is reflected to make an angle of 1° with its original direction. If the distance between the mirror is 6250 m, calculate the velocity of the light.
