WebThe Grating Equation. (1) This is the well-known Grating Equation. For a given angle of incidence, θ, it gives the angle of diffraction θ m for each “order” m for which a solution to (1) exists. Often gratings are described by the frequency of grating lines instead of the period, where f (in lines/mm) is equal to 10 6 /Λ (for Λ in nm).

WebIn this step, we are calculating the crude, age-specific rates. A crude incidence rate is the number of new cancers of a specific site/type occurring in a specified population during a year, usually expressed as the number of cancers per 100,000 population at risk. It is calculated using the following formula: Age. Count. Population. Crude Rate. WebExpert Answer.

WebApr 7, 2024 · Answer: Incidence rate is equal to no. of new cases/population at risk * population size. Let's go over an example: During one year, 12 men out of a population of 50,000 healthy men were newly diagnosed with colorectal cancer. Thus, our population size is 50,000. Then, the colon cancer incidence rate is equal to 24 per 100,000 men per year.
