This causes line emission spectra to be produced, as shown below. This is not a continuous spectrum as only light of specific frequencies and specific colours are produced. Different types of ...

The spectrometer works best in darkness, though the black panels help if turning off most of the lights is impractical. The black panels should block everything on the camera's right-side field of ...

When a gas is very hot, it doesn’t emit all wavelengths of light. Hot gases don’t produce a continuous emission spectrum. Black hydrogen absorption lines are at the same wavelength as the ...

A research team from Skoltech and ITMO university has obtained tunable polariton emission at room temperature on CsPbBr3 ...

A NEW series of observations of the galactic radio emission has been conducted at the frequencies of 20, 30 and 85 Mc/s. These low-resolution observations made with scaled aerials were intended to ...
