Of the colors in the visible spectrum, red has the lowest frequency and the longest wavelength. As you move on up the spectrum, wavelengths get shorter. Red has the longes â¦ t spectrum of all visible light. But infrared is even longer and there are many more colors but you can't see them.
1 The average age of patients diagnosed with skin cancer is dropping, from 50 to 40 years old. 2  Approximately 75 percent of damage to your skin from the sun happens by the time you are 20 years old. 3  More than 90 percent of all skin cancer cases are due to overexposure to sunlight.
Skin cancer (malignant melanoma) is the fifth most common cancer in the UK (around 13,300 people were diagnosed with malignant melanoma in 2011), and the disease accounts for 1% all cancer deaths (around 2,100 people died in 2012).his is a rough estimate, however, as good statistics are not kept. Of nonmelanoma skin cancers, about 80% are basal-cell cancers and 20% squamous-cell cancers. Basal-cell and squamous-cell cancers rarely result in death. In the United States they were the cause of less than 0.1% of all cancer deaths.
