- What is the only statement that correctly identifies the ability of different wavelengths of UV light to penetrate the human skin? Note: UVA is the longest wavelength (least energy), and UVC is the shortest wavelength (most energy). If you've studied the electromagnetic spectrum you may remember that wavelength and energy have an inverse relationship. We'll talk more about this later in the course. Group of answer choices A- UVA light penetrates only as deep as the epidermis, which is where it has its effect B-UVB light penetrates only as deep as the epidermis, which is where it has its effect C-UVC light penetrates only as deep as the epidermis, which is where it has its effectarrow_forwardCHOOSE FROM THE FOLLOWINGYou should always position the cells or tissues in the center of view before increasingmagnification, because.A. You know that the image will move right as you move the slide to the left.B. You know that the image will move up as you move the slide down.C. You know that the center of the field of view will be unchanged.D.
