Question

A student was observing an emission spectrum of a substance and observed a number of series of spectral lines. One of these series consisted of four spectral lines in the visible region, where each spectral line had its own distinctive color that is, red, blue-green, blue-violet and violet. The illustration of the emission spectrum. Based on these observations, assist the student in answering the following questions. i) Name of Series: iii) Name of the substance

Answer 1

Answer:

take it

Explanation:

The photoelectric effect provided indisputable evidence for the existence of the photon and thus the particle-like behavior of electromagnetic radiation. The concept of the photon, however, emerged from experimentation with thermal radiation, electromagnetic radiation emitted as the result of a source’s temperature, which produces a continuous spectrum of energies. More direct evidence was needed to verify the quantized nature of electromagnetic radiation. In this section, we describe how experimentation with visible light provided this evidence.
