Answer:
A) True
Step-by-step explanation:
Blue light is on the frequency of visible light (also known as visible spectrum) that comes from around 400 nm to 700 nm, the blue light is close to 400 nm is relatively short but if we compare blue light against X-rays, the X-rays only have around 0.1 nm or 10 nm, that's really small, for that reason the x-ray can go throuhgt your body and it's used to reveal what is inside of you in the radiogarphs.
So, blue light has 400 nm frequency that is higher than the 10 nm of the X-ray
