Theory of Light:
Newton proposed 'Corpuscular Theory of Light'.
2. According to corpuscular theory, light consists of a stream of tiny, light and perfectly elastic particles called 'corpuscles'.
3. The velocity of light is different in different media.
4. According to the corpuscular theory of light, various colours of light are supposed to be due to different sizes of corpuscles.
5. Corpuscular theory could not explain the phenomena of interference, diffraction and polarization of light.
6. According to Huygens' theory, light travels in the form of waves.
7. The basis of Huygens' wave theory of light is his principle concerning construction of wavefront.
8. The imaginary three dimensional surface formed by the particles of a medium which are vibrating in the same phase is called a 'wavefront'.

Find the lowest frequency for which destructive interference Two loudspeakers, A and B, are driven by the same amplifier and emit sinusoidal waves in phase. Speaker B is 2.00 m
if in an interference pattern,the ratio between maximum and minimum intensities is 36:1,find the ratio between the amplitude and intensities of the two interfering waves.
Using cross belts cross the belt on the spool pulleys used in C 1 above and turn one of the pulleys. Note that they now turn in opposite directions.
Q. Orbital Velocity for Low Earth Orbit Neglecting air friction an object will sustain a low altitude orbit when the centrifugal force due to its motion in a circular orbit is
