What are the seven different types of light visible to humans?

Colors of the Visible Light Spectrum

Violet - shortest wavelength, around 400-420 nanometers with highest frequency.  

Indigo - 420 - 440 nm.

Blue - 440 - 490 nm.

Green - 490 - 570 nm.

Yellow - 570 - 585 nm.

Orange - 585 - 620 nm.

Red - longest wavelength, at around 620 - 780 nanometers with lowest frequency.

If these are the missing choices: a. to determine skin temperature, place the back of your hand against the patient's skin.b. determine body temperature by touching the patient's hands and feet.c. skin temperature will tell you very little about this patient's condition or well-being.d. the patient's skin temperature and color will likely be warm and red.my answer is: a. to determine skin temperature, place the back of your hand against the patient's skin. using the back of the hand to check for temperature rather than the palm is more effective because the back of the hand has more nerves that can feel and transmit the temperature than the palm.
