A

Aka violet ray— thermal or heat-producing current with a high rate of oscillation or vibration

17
Q

Tesla high frequency current

A

does not produce muscle contractions and its effects can be either stimulating or soothing depending on the method of application

18
Q

Visible light

A

Part of the electromagnetic spectrum that we are able to see

19
Q

UVA– ultraviolet light

A

Has the longest wavelength of the UV light spectrum and penetrates directly into dermis of the skin, damaging the collagen and elastin

20
Q

Broad spectrum

A

Broad spectrum sunscreen protects from both UVA & UVB

21
Q

Lasers

A

All lasers work by selective photothermolysis, a process that turns the light from the laser into heat
