Human eye is able to sense electromagnetic waves with frequency range 8 x 1014 Hz to 4 x 10 14 Hz. The highest frequency is for violet and the lowest is for red. Hence we use the order VIBGYOR for visible range.
The frequencies higher than 8 x 10 14 Hz will be termed as ultra violet and those less than 4 x 10 14 Hz as infra red.
So, these radiations cannot be sensed by the human eye, in general. Other waves not visible to human eye are:
X-rays, Gamma rays which are having higher frequency than ultra violet and micro waves, radio waves which are having frequency lower than infra red.

What are the differences between visible light and infrared radiation in terms of their properties and applications?
Visible light and infrared radiation differ in their wavelengths and energy levels. Visible light has shorter wavelengths and higher energy, allowing us to see colors and objects. Infrared radiation has longer wavelengths and lower energy, making it invisible to the human eye but useful for applications like thermal imaging, communication, and heating.
Why is radiation invisible to the human eye?
Radiation is invisible to the human eye because it has a wavelength that is outside the visible spectrum. This means that the energy emitted by radiation is not within the range that our eyes can detect, making it invisible to us.
What kind of radiation do we experience as invisible heat?
Invisible heat radiated from objects is in the form of infrared radiation. This type of radiation is not visible to the human eye but can be felt as heat when it strikes the skin.
What is the invisible heat from the sun called?
The invisible heat from the sun is called infrared radiation. This type of radiation is not visible to the human eye but can be felt as warmth on the skin.
What do visible and invisible energy compose?
Visible energy refers to the forms of energy that are easily detectable by our senses, such as light and heat. Invisible energy includes forms like electromagnetic radiation, radio waves, and gravitational forces that are not directly perceptible to us but still play crucial roles in the functioning of the universe.
What is the differences between visible and invible radiation?
Radiations within the range of 200 - 400nm are Visible Radiations. And others out of this range are invisible radiations.
Is ultraviolet radiation visible or invisible?
By definition, ultra-violet light is outside the visible spectrum of EM radiation. Thus it is defined as invisible.
What type of heat transfer is invisible and visible lights?
radiation

Do invisible flames give off light?
Invisible means there is no visible light. They may give off other electromagnetic radiation, but "light" usually refers to visible light.
What is the largest invisible object?
The electromagnetic radiation (excluding the visible range) that pervades the universe.
What lamp will show invisible heat radiation?
An infrared lamp will show invisible heat radiation. Infrared lamps emit infrared light, which is not visible to the human eye but can be felt as heat due to its longer wavelength compared to visible light.
What does fluorescent?
Fluorescent means something is glowing, usually with visible light. Fluorescent means giving off visible (or invisible) radiation as a result of absorbing shorter wavelength radiation.
