Question

Which type of spectrum of neon lamp

Answer 1

Explanation:

Neon light emit wavelengths specific to the atoms in the bulb with little or no wavelengths in between. Photon. False because, Blue light has smaller wavelength, higher energy, while red light has a longer wavelength with lower energy.

Answer 2

Neon lamp produces a discrete spectrum.

Explanation:

• Spectrum of Neon lamp lies in the visible region and it emits a distinctive orange glow.

• The discrete spectrum takes only distinct values with gaps between one value and the next.

• Neon lamp consists of neon gas which is present at low pressure.

• In the neon tube, the electrodes are insulated from both sides.

• These are used in traffic signals because of their distinct glow.

• These are also used in Microwave detector, LED, LCD and in Logic circuits.

• It was developed by Daniel Moore.

• When proper voltage is applied between the electrodes, the lamp produces an orange glow these are better than incandescent lamps.

Monochromatic radiation of wavelength 640.2 nm (1nm = 10−9 m) from a neon lamp irradiates photosensitive material made of caesium on tungsten. The stopping voltage is measured to be 0.54 V. The source is replaced by an iron source and its 427.2 nm line irradiates the same photo-cell. Predict the new stopping voltage.
