Your question is too vague to be answered. The word "risk" is invoked when there is some objective that is to be accomplished. Is your objective the perception of light by human eyes, the detection of distant galaxies, the successful developing of photographic film, etc?
Visible light waves are beneficial for the human race, in that they make it possible for usto see stuff as we go through daily life, helping us immeasurably to avoid the dangerousand embarrassing risks of bumping into things, falling over things, stepping in stuff, andgenerally stumbling around blindly. In modern times, these waves are also utilized in thetraffic signals at major intersections, which are responsible for keeping vehicular trafficflowing smoothly and with equanimity.
The only part of the electromagnetic spectrum that we can see is the small yet significant part of visible light. Visible light is not harmful for humans, but some of the other types of waves are.
Light is both Visible, and Invisible. It depends on what frequency of light it is, and also what Species you are. For example, we Humans can't see ultra violet light but some animals, like Snakes, can see it.
The visible light contains wave lenghts from 200nm to 800nm. 200 nm corresponds with the violet/blue colour and 800nm and around corresponds with red colour. Above 800nm wave lenght of the light is called infrared and below 200nm - ultraviolet. The shortest the lenght, the higher the energy. After ultraviolet we have radio waves, micro waves, X-rays, etc.
Examples of electromagnetic radiation include radio waves, microwaves, infrared light, visible light, ultraviolet light, X-rays, and gamma rays. Visible light is a specific range of electromagnetic radiation that our eyes can detect, falling between ultraviolet and infrared light on the electromagnetic spectrum.

for wavelength, the longer of the two is visible light, but the longest type of rays are radio waves (some of them have a wavelength as long as a football field)
radio waves
Visible light because some of the energy that reaches the earth from the sun is visible light. The visible light from the sun is white light. White light is visible light of all wavelengths combined. Light from lamps in your home as well as from the fluorescent bulbs in your school is also white light.
No, not all electromagnetic waves are invisible. While some, such as radio waves, microwaves, and infrared waves, are invisible to the human eye, others, like visible light, ultraviolet light, and X-rays, can be seen or detected with the right equipment. For example, visible light waves are responsible for the sense of sight.
The most visible electromagnetic waves on Earth are visible light. This type of electromagnetic radiation is the only part of the electromagnetic spectrum that is visible to the human eye. Visible light is responsible for the colors we see in the world around us.
All the things I look at are reflections of visible light waves. I seldom get more than waist deep in the ocean waves. The wind waves over a mountain are shown by hogsbacks, or cumulo-nimbus clouds - strongly striated and layered horizontal clouds continuously forming at the leading edge and vanishing at the trailing edge.

Examples of transmission waves include radio waves, microwaves, infrared waves, and visible light waves. These waves are used to transmit information and energy through various mediums.

Visible light waves are electromagnetic waves, within a certain range of frequencies. The wavelength of visible light is between about 400 and 700 nm. Some of the characteristics of electromagnetic waves include:* Carried by particles called photons* The wave is a wave in the electric and magnetic fields* In a vacuum, this wave (and the photons) propagates at the so-called speed of light, which is about 300 million meters/second.
