Light is essential to our lives, whether it is brightening when the sun rises or turning on the lights when it gets dark at night. <\/p>\n\n\n\n

You may not have paid much attention to light because you take its existence too much for granted.<\/p>\n\n\n\n

Did you know that there are different types of light? We would like to explain about it more clearly.<\/p>\n\n\n\n

\u00a0<\/div>\n\n\n\n

‘Light’ is a type of electromagnetic wave.<\/h2>\n\n\n\n

Electromagnetic waves are waves of energy generated where an electric current runs and a voltage is applied.<\/p>\n\n\n\n

The term \u2018electromagnetic wave\u2019 may be unfamiliar to some, but our lives are made convenient by the use of it from microwave ovens, mobile phones and other sources.<\/p>\n\n\n\n

We can listen to the radio and watch television thanks to the reception of electromagnetic radiation.<\/p>\n\n\n\n

There are some types of Electromagnetic wave as follows.<\/p>\n\n\n\n

Radio wave: Used for radios, televisions, microwave ovens, etc.
Infra-red rays\uff1a Used for warming things up, etc.
Visible ray\uff1a The ‘light’ we see.
Ultraviolet rays\uff1aUsed for sterilization, etc.
X-ray\uff1aX-rays, etc.
Gamma ray\uff1aUsed for crop breeding and cancer screening.<\/p>\n\n\n\n

Among these electromagnetic waves, infra-red and visible light and ultraviolet radiation are referred to as ‘light’.<\/p>\n\n\n\n

Infrared and ultraviolet radiation are invisible to the eye but are ‘light’.<\/p>\n\n\n\n

Each Electromagnetic wave has the wave properties which are determined by the distance from wave head to wave head (one wave length) called wavelength.<\/p>\n\n\n\n

The radio wave has longer wavelengths, shorter wavelengths are for ultraviolet rays and much shorter wavelengths are for X-rays and \u03b3-rays.<\/p>\n\n\n\n

SUGA’s photoemission electron microscope makes it possible to visualize the electronic state of a sample’s surface by irradiating it with short-wavelength ultraviolet light.<\/p>\n\n\n\n

Although UV radiation is often demonized as a cause of sunburn, it plays a great role in research.<\/p>\n\n\n\n

Your impression of UV radiation may change.<\/p>\n\n\n\n
