Essays on Radiant Energy

Aim: The aim of this project is to determine the influence of sunlight and shade on the characteristic of leaf morphology. Background: The gradient in light received by the leaves, compel them to adapt for optimum growth in a particular environment. This adaptation takes place gradually, with changes in certain morphological features. These morphological changes that take place with time and space in which the plant grows is defined as succession and has a role to play in evolution. Certain environmental factors like shade and sunlight can present as a slightly adverse condition that affect plant growth. In order ...

Introduction

There are environmental chemical processes which require light to react. These processes are called photochemical reactions. Photochemical reaction is commonly initiated due to the absorption of solar energy or light. When molecules absorb energy in the form of light, the atoms are converted in a transient excited state (Larson & Weber, 1994). This transition state or excited has completely different physical and chemical properties with the initial state of the molecule. The excited states also have more tendencies to react since they are considered stronger acids and stronger reductants that the initial state of the molecule. The excited state of ...

If someone has made an invention to make life easier or to alleviate one’s living condition then the security of the patent for that invention is needed. According to the World Intellectual Property Organization, a patent is an exclusive right of a person for producing something that offers a new solution to a problem. Furthermore, a patent provides the maker with protection for their invention, and this protection usually lasts for 20 years. One privilege of a person who has a patented invention is that the invention cannot be sold, distributed, used or commercially made without the inventor’s consent. This right is usually enforced ...

Stars can be considered as the most attractive and the most recognized object that can be identified in the galaxy. They can be easily distinguished through their bright-colored and shiny appearance whenever we try to look at it at night. Basically, stars are born within the clouds of dust scattered in different locations in the Earth’s galaxy. Generally, the larger the star, the shorter its life is.

Describe what triggers a star leaving the main sequence:

The general theory why stars prefer to leave the main sequence is that when the Hydrogen fuel core is being consumed, energy is being released; permitting the radiant energy to pass ...

Introduction

With people becoming more conscious of the detrimental effects of fossil fuel, the demand for green sources of energy is on a rise. The Sun is the source of all the energy in this world. Even if a small percentage of solar irradiance is collected every day then all the problems related to the scarcity of sufficient energy will be solved. However, it is not very easy to collect and store solar energy in an effective way. Solar Collectors also known as Solar Thermal Collectors are designed to absorb solar energy from solar radiation which is then reduced to heat water ...
