In physics, a closely related quantity called  optical depth  is used instead of absorbance: the natural logarithm of the ratio of incident to transmitted radiant power through a material. The optical depth equals the absorbance times ln(10).The term absorption refers to the physical process of absorbing light, while absorbance does not always measure absorption: it measures attenuation (of transmitted radiant power).he optical depth equals the absorbance times ln(10). The term absorption refers to the physical process of absorbing light, while absorbance does not always measure absorption: it measures attenuation (of transmitted radiant power).
What is Automation? Automation is one of the most useful features of REAPER. It enables you to ensure that when your project is played back, changes in such things as volume level or panning for different tracks can be remembered and played back in real time, with the project.
Automation testing is an Automatic technique where the tester writes scripts by own and uses suitable software to test the software. It is basically an automation process of a manual process. Like regression testing, Automation testing also used to test the application from load, performance and stress point of view.In other word, Automation testing uses automation tools to write and execute test cases, no manual involvement is required while executing an automated test suite.utomation testing is a best way to fulfill most of the testing goals with effective resources and time. But be careful before purchasing the automation tool that fulfills the requirement of the application because no any tool can fulfill 100% requirement.
