Dispersion and Impure Spectrum:
Dispersion : The phenomenon due to which a polychromatic light splits into component colours, when passed through a prism is called 'dispersion'.
Impure Spectrum : A Spectrum in which various bands of colours have no sharp well defined boundaries, but merge in each other is called 'Impure Spectrum'.
Pure Spectrum : A Spectrum in which various bands of colours have sharp well defined boundaries and do not merge in each other is called 'Pure Spectrum'.
The angle through which light of particular wavelength can deviate, while passing through a prism is called 'Refrangibility'. The refrangibility for red light is least whereas for the violet light is maximum.
Wavelengths of g - rays are ranging from 0.0001nm to 0.1 nm. (or) 0.001 A to 1A0
Q. What are de Broglie waves? Matter in motion should be accompanied by waves called de Broglie waves. de Broglie wavelength λ = h / mv
how can sensitivity curve b measured?
derive an expression for time of flight of horizontal projectile
Explain the first law of thermodynamics. Reduce its mathematical form, give the first law equation for different processes. What are its limitations?
One source of a star's energy is the fusion of two deuterons to form an alpha particle plus a gamma ray. a. Write down the nuclear equation for this fusion. b. Measure the m
Refractive index: The most important optical measurement for any transparent material is its refractive index (n). The refractive index is the ratio of the speed of light (c)
It contains 35%- 90% nickels. Higher is the nickel content higher is the permeability and lower is the magnetic saturation of the alloy. MN, CO, and Mo can also be added in trace q
The frequency of a wave is 50 Hertz and its wavelength is 25 meters. What is the velocity of this wave? Ans: The velocity of given wave is 1250 meters/second.
Explain about the transmission electron microscope. The Transmission Electron Microscope Transmission electron microscopy (TEM) is a microscopy method; a beam of electrons i
