Ultraviolet light is typically divided into threecategories. UV-A, with wavelengths between 400 nm and 320 nm,has been linked with malignant melanomas. UV-B radiation,which is the primary cause of sunburn and other skin cancers,has wavelengths between 320 nm and 280 nm. Finally, the regionknown as UV-C extends to wavelengths of 100 nm. (a) Find therange of frequencies for UV-B radiation. (b) In which of thesethree categories does radiation with a frequency of 7.9 * 1014 Hzbelong?

The star Sirius is much hotter than the sun, with a peak wavelength of 290 nm compared to the sun’s 500 nm. It is also larger, with a diameter 1.7 times that of the sun. By what factor does the energy emitted by Sirius exceed that of the sun?
Assume the mostly infrared radiation from a heat lamp acts like a continuous wave with wavelength 1.50 µm . If the lamp’s 200-W output is focused on a person’s shoulder, over a circular area 25.0 cm in diameter, then how long will it take to increase the temperature of the 4.00-kg shoulder by 2.00°C, assuming no other heat transfer and given that its specific heat is 3.47 × 103 J/kg. °C ?
AM radio waves can be produced by a marconi anthenna, whose length must be one-fourth of the wave's wavelength. What must be the length, in meters, of the antenna to produce a frquency of 630kHz?
A radiometer has two square vanes (2.0 cm by 2.0 cm), attached to a light horizontal cross arm, and pivoted about a vertical axis through the center. The center of each vane is 12.0 cm from the axis. One vane is silvered and it reflects all radiant energy incident upon it. The other vane is blackened and it absorbs all incident radiant energy. Radiant energy, having an intensity of 600 W/m2 , is incident normally upon the vanes. What is the radiation pressure on the blackened vane?

Just after detonation, the fireball in a nuclear blast is approximately an ideal blackbody radiator with a surface temperature of about 1.0*107 K. (a) Find the wavelength at which the thermal radiation is maximum and (b) identify the type of electromagnetic wave corresponding to that wavelength. This radia-tion is almost immediately absorbed by the surrounding air molecules, which produces another ideal blackbody radiator with a surface temperature of about 1.0 * 105 K. (c) Find the wavelength at which the thermal radiation is maximum and (d) identify the type of electromagnetic wave corresponding to that wavelength.
