That would be position Y, as the northern hemisphere is tilted away from the sun.
What is this on, is this on a test?
Answer: smaller
Ultraviolet radiation has broad range of wavelengths, higher
number means greater risk of exposure to UV rays that can be dangerous to skin
cells. Sunlight is the main source of electromagnetic radiation and it is
transmitted in different wavelengths known as electromagnetic spectrum. This spectrum
is divided into several regions in order of decreasing wavelength and increasing
energy and frequency. UV radiation has frequency and energy that is higher than purple
light or violet radiation and the wavelength of ultraviolet radiation
is smaller than violet radiation.
