Is the following statement true about the Lyman spectral series? Statement Lyman series lies in the ultraviolet region

Correct Answer: Statement is true
The Lyman series lie in the ultraviolet region because when the hydrogen electron becomes excited to a higher energy level and then falls to the ground state, if it falls to n=1 energy level, then a photon is emitted by the electron. This transition from a higher energy level to n=1 is part of the Lyman series.

The ultraviolet spectral region is obtained in Balmer series.

From an alloy, two specimens are machined and tested separately under tension and compression. The engineering stress-strain curves as well as the true stress-true strain curves for tension and compression are plotted in the same diagram. Identify the correct statements:
P. The engineering stress-strain curves in tension and compression are identical.
Q. The true stress-true strain curve in compression is lower than the true stresstrue strain curve in tension due to Bauschinger effect.
R. The true stress-true strain curve in tension is above the corresponding engineering stress-strain, curve.
S. The true stress-true strain curve in tension and compression are identical.
