Is it possible to see a full circle of a rainbow from Earth?
Rainbow occurs due to reflection and splitting of sunlight from small water droplets.Calculation shows that if in atmosphere enough droplets is present then you can see rainbow if you stand with your back facing the sun at an angle of 40 - 42 degree with the line connecting your head and its shadow on ground ,called antisolr point( see figure).Hence a rainbow is actually observable in circle around this line. But due the the presence of ground we can see only upper half of it. However, if you ever be in a airplane with proper condition of rainbow in atmosphere you can be lucky to see a full circle.
Explain the phenomenon of a rainbow. How are you able to see a rainbow? What are the conditions for a rainbow to occur?
(b) In the primary rainbow, does the observer see the green bow at a lower or higher angle than the yellow bow? Explain (i) why this is, and (ii) explain the main physical processes producing a primary rainbow
Spaceship A moves away from Earth at a speed vA = 0.776c (see figure). Spaceship B pursues at a speed vB = 0.891c relative to Earth. Observers on Earth see B overtaking A at a relative speed of 0.115c. With what speed is B overtaking A as seen by the crew of spaceship B?
Spaceship A moves away from Earth at a speed vA = 0.728c (see figure). Spaceship B pursues at a speed vB = 0.981c relative to Earth. Observers on Earth see B overtaking A at a relative speed of 0.253c. With what speed is B overtaking A as seen by the crew of spaceship B?
Please answer! We can see rainbow in the sky because the sunlight, while traveling through the water droplets, undergoes: Diffraction; Total internal reflection; Dispersion; Interference; None of the above.

A lighthouse sweeps its beam of light around in a circle once every 9.6 s. To an observer in a spaceship moving away from Earth, the beam of light completes one full circle every 18 s. What is the speed of the spaceship relative to Earth?
