Whenever I need an app to get a specific work done, I search it and find it in almost no time. I use youtube mostly to listen to islamic lectures and sometimes nasheed. So, I usually need the youtube audio only, not video. But there is no way to turn video off and keep the audio only in the official youtube app. A lot of internet data, battery charge is consumed that way. You cannot play video in the background on your smartphone; if you shut the screen off, the video will be off. These problems were annoying and at last I found an app. The name of the android app is YMUSIC , made by XDA developers. Why is it special to me? As I was deprived of the features while using the official app, I was very happy upon finding the app. It includes all the features I dreamed of before using it. The features are: Only audio is loaded, no video. But you can turn on the video if you w

The answer: If you have very little knowledge of science, you have to understand some easy facts first. The facts: 1. Sunlight is a composite ray. This is why we see a rainbow. The white ray of the sun is composed of 7 visible colors (violet, indigo, blue, green, yellow, orange, and red) along with other rays (x-ray, infrared ray, etc.). You can test it yourself with a prism. Image source: youtube.com Image source: rookieparenting.com 2. Light spreads like a wave. So, sunlight is a wave that is composed of different waves or rays. Different waves are of different wavelengths. The shorter the wavelength of a wave is, the more it is scattered by particles (gas, dust, etc.). And the longer the wavelength of a wave is, the less it is scattered by particles. Thus, a wave with a shorter wavelength can pass a longer distance. 3. Blue light waves are shorter

Sometimes I can’t concentrate on my work because of a lot of thoughts in my brain; I usually think, “I’m gonna forget these important tasks I have to do”; this kind of thinking interferes with my work. This is why I always keep a notepad or use a notepad app on my phone. This helps me stay free of stress and tension. Why is colornote special? I used a lot of other apps on my smartphone to keep notes, but there were problems I couldn’t tolerate. I am listing some apps with their pros and cons. Evernote: A nice app with sync, but heavy (takes much space and ram). The loading time is boring. Contains too many features that I don’t need. Google keep: Almost similar to evernote, but it's also a heavy app. Some other lightweight, small notepad apps: Fast and small, but lack sync feature. Sync feature is essential for me. If I need to restore my phone or change my smartpho
