nd on A sample is bombarded by incident X-rays, and free electrons in the sample scatter some of the X-rays at an angle of 8-130.0° with respect to the incident X-rays, as shown in the drawing. The scattered X-rays have a momentum whose magnitude is 1.861 x 1024 kg-m/s. Determine the wavelength (in nm) of the incident X-rays. (For accuracy, use h = 6.626 x 1034 J-s, c -2.998 x 10 m/s, and m= 9.109 x 1031 kg for the mass of an electron.) Number i 33237 m Photon scattering from stationary electron Units nm H Search POD

One of the first signs of sunburn is the reddening of the skin (called erythema). As a very rough rule of thumb, erythema occurs if 14.0 mJ of ultraviolet light of approximately 308 nm wavelength (referred to as UVB radiation) is incident on the skin per square centimeter during a single exposure. How many photons are incident on 1.00 cm2 of skin in this amount of exposure? photons
