irradiance

Vocabulary Word

Definition

'Irradiance' is a measure of the intensity of radiation being received. It's the amount of energy or light that comes to one square meter in one second. It helps explain how bright or strong light feels.

Examples in Different Contexts

In physics, 'irradiance' is crucial for studying the properties and effects of light and other electromagnetic waves. A physicist might state, 'We measured the irradiance to quantify the amount of solar energy received at the surface.'

Practice Scenarios

Electrical Engineering

Scenario:

For these solar panels, peak efficiency is critically important. Let's test them around midday when sunlight intensity is the greatest.

Response:

Yes, we should also calculate their irradiance at different times of the day to assess the overall performance.

Physics

Scenario:

Our experiment needs a very consistent light source. The rate of flow of energy is essential for us to get the result accurately.

Response:

I agree. We need to select a light source with a consistent and high irradiance for precision.
