In the case of a spectrometer, a circular scale graduated in half a degree is attached with _.
Correct answer: B. Turntable
- A. Telescope
- B. Turntable
- C. Cross wire of telescope
- D. None of these options are correct
Explanation
In a spectrometer, the circular scale graduated in half degrees is typically attached to the turntable. The turntable is the component of the spectrometer that allows precise rotation of the sample or the prism, enabling measurements to be taken at different angles. Attaching the scale to the turntable ensures that the angle of rotation can be accurately measured and read from the scale.

About Dawn of Modern Physics
Classical physics cannot explain blackbody radiation and related observations, leading to Planck’s quantum theory, in which energy is emitted or absorbed in discrete packets. Photons provide the particle model of light, with energy and momentum linked to frequency and wavelength, including the photoelectric effect and its threshold frequency.
