If the earth did not have atmosphere, would its average surface temperature be higher or lower than what it is now? Explain.
A wave has a wavelength of 10-3 nm. Name the wave.
Name three properties of ultraviolet radiations which are similar to visible light.
The figure shows the intensity-wavelength relations of X-rays coming from two different Coolidge tubes. The solid curve represents the relation for the tube A in which the potential difference between the target and the filament is VA and the atomic number of the target material is ZA. These quantities are VB and ZB for the other tube. Then,
The Kβ X-rays from certain elements are given below. Draw a Moseley-type plot of √v versus Z for Kβ radiation.
| Element | Ne | P | Ca | Mn | Zn | Br |
| Energy (keV) | 0.858 | 2.14 | 4.02 | 6.51 | 9.57 | 13.3 |
State two uses of infrared radiations.
