sponge filter in a fish tank
For some reason, people overlook the aquarium sponge filter and go for a more complex system such as those fancy ultraviolet sterilizers for fish tanks, which not always works better than the simple sponge.Although sponge filters have been around for so many years, only a few know or have an idea of what they are, what they do and how...
man combining colors in rgb and cmyk
There are two primary color systems in the print and digital design industries: RGB and CMYK. Conveying the right message via your designs is crucial and possible, but only if you use the right colors.Color has always been a significant part of everyday life from time immemorial. It is so inherently powerful that it can affect your mood or...
how does an infrared themometer work
Infrared radiation is electromagnetic radiation that is invisible to the human eyes, compared to the visible light spectrum.It has frequencies that range from less than one hertz to over 1025 hertz and corresponds to wavelengths from thousands of kilometers to a fraction of half the size of an atomic nucleus.IR was discovered in 1800 by William Herschel when he was...

Here’s a shocker for you; you may not realize it, but, your skin is covered in stripes, much like those on Zebra and tigers. Thankfully, these lines are invisible and on a healthy skin can only be seen with the aid of ultraviolet rays or black light.However, the stripes are decidedly visible if you are suffering from a number...

People who lived in ancient times have always believed in the healing power of light as an intriguing source of treatment. Modern-day scientific discoveries have confirmed that light therapy can fight back signs of aging and also do wonders to the human skin.The study led by NASA (National Aeronautics and Space Administration) has opened up numerous possibilities for the...
lightning
You’ve heard it and have probably said it too – lightning does not strike in the same place twice. Well, the fact is, it does and can hit the same spot twice – at least records show that the Empire State building is struck an average of 23 times every year.Humanity has always been fascinated by the immense beauty...
speed of light
Technological advancements in space travel, hyperbole cars, communications, satellite technologies, sciences and research, and even in defense and military programs are based on the assumption that the speed of light is the fastest matter can travel.The assumption is that nothing except well, it can actually travel with the speed of light. As an object (particle) approaches it, it decomposes...

For centuries farmers have taken advantage of the beneficial relationship between some bacteria and plants to boost yield, improve soil fertility, and inhibit crop infections.Today spirited efforts are ongoing towards sustainable crop production and at its core is the application of biological approaches as part of an integrated crop nutrient management system. In fact, there is a piling body...
cellular respiration process in plants
Cellular respiration is a metabolic process that takes place at the cell level in both plants and animal cells. It is the chemical process used by cells to unlock energies stored in starch into usable forms.Remember during photosynthesis they convert light energy into starch which is then stored for future use. Cellular respiration is more intense for indoor plants...
tree in summer with light on it
All living things require "fuel" in one form or the other to survive. However, in this article, we are going to be focusing on plants. We’ll look at how plants gather raw materials for their energy synthesis; what photosynthesis is all about; and in which form energy is stored in herbs.But, first, let us go back to the beginning....
Plants need light for photosynthesis and growth. However, not all light is useful to plants. In fact, some are outrightly harmful and dangerous to them.Is UV light useful or harmful to plants? That’s the question this article aims to answer.But first, what is UV light? An ultraviolet ray is that part of the electromagnetic spectrum which falls between the...
Photosynthetically active radiation
Starting an indoor garden could be a fun and sustainable method to grow those fresh vegetables you need during summer months when there is an insufficiency of sunlight. And just as every farmer knows (sure you’re one) – plants need sunlight, in fact, plenty of light to grow, bud, flower, and to yield bountiful produce.Figuring out how to supply...
Ultraviolet radiation is a part of the sunlight spectrum that reaches the earth. It has wavelengths shorter than visible light, making it invisible to the naked eye. The UV light has a wavelength between 10 to 400nm.The UV light is broken down into three types of UV bands: UVA, UVB, and UVC.They decrease in wavelength from A to C,...
If you ever wondered how UV light kills bacteria, search no more. You're in the right spot. Ultraviolet light, through the sanitization process and packed into the right device(I would mention here UV air purifiers, ultraviolet wands, toothbrush sanitizers or UV phone sanitizers), can be used to kill germs and bacteria.Bacteria are a group of single-celled microorganisms that reproduce through cell...
When reading about Ultraviolet radiations, there are these two terms that seem to be confusing; UV Light and Blue Light. To understand The Difference between UV Light and Black Light, it’s essential to know what each of them means. Today, am going to help you understand the difference. To begin with, let’s understand the definitions of these terms.  Definition of...
