What does gravitational force depend on?
Gravitational force depends on mass and distance.
Therefore, the formula for calculating gravitational force among two objects with a given distance: G [(mass 1) (mass 2)]/distance squared. G is universal gravitational constant: 6.67x10 raised to -11 power.
The dimentional formula of plank;s constant ML 2 T -1
Define term coherence as the characteristics of laser. Coherence: The light from a laser is called be highly coherent that implies the waves of laser light are in similar
Define about the set-up of Helium-Neon Laser. The laser radiations along with higher coherence, higher directionality and higher monochromacity can be obtained from this. But,
#questi1. A sound with a frequency of 261.6 Hz travels through water at a speed of 1435 m/s. What is the wavelength of the wave? a. 1.83 x 10 -1 m b. 3.753 x 10 5 m c. 5.486 m
Depending upon the penetration power, there are two parts of X-rays Hard X-rays More penetration power More frequency of the order of ≈ 1019 Hz Lesser wavelength range
