Answer:

alternating current

Question 8: called the 'burning' light, associated with sunburns

Answer:

UVB light Question 9: blocked by ozone layer. Shortest wavelengths of UV light, but if ozone layer was depleted these could do a the most damage

Answer:

UVC light Question 10: introduces water soluble products into the skin with electric current (types: cata- & anaphoresis)

Answer:

iontophoresis
