Physics

Matter waves are De Broglie waves.

1 Joule is equal to 10^7 ergs.

Magnetic resonance imaging (MRI), nuclear magnetic resonance imaging (NMRI), or magnetic resonance tomography (MRT) is a medical imaging technique used in radiology to visualize internal structures of the body in detail. MRI makes use of the property of nuclear magnetic resonance (NMR) to image nuclei of atoms inside the body. An MRI scanner is a device in which the patient lies within a large, powerful magnet where the magnetic field is used to align the magnetization of some atomic nuclei in the body, and radio frequency fields to systematically alter the alignment of this magnetization. This causes the nuclei to produce a rotating magnetic field detectable by the scanner—and this information is recorded to construct an image of the scanned area of the body.

The velocity of sound in air decreases with decrease of temperature.

According to Rutherford’s atomic model, the electrons inside an atom are not stationary.

The liquid surface falls down on the direction of motion and rises up on the back side of the tank.

Red and green is the most convenient combination during day and night time because of very precise visibility.

Nuclear Fission is caused by the impact of neutron.

Eclipses occur due to rectilinear propagation of light.

Bubbles of air rise up through liquids due to viscosity and buoyancy.
