1. What is Transmitted Radiation?

Transmitted radiation is the amount of radiation energy that passes through a material or medium per unit surface area. It represents the portion of incident radiation that is not absorbed or reflected by the material.

2. How Does the Calculator Work?

The calculator uses the formula:

\[ \text{Transmitted Radiation} = \text{Transmissivity} \times \text{Incident Radiation} \] \[ G_{tr} = \tau \times G \]

Where:

\( G_{tr} \) — Transmitted Radiation (W/m²)
\( \tau \) — Transmissivity (unitless, 0-1)
\( G \) — Incident Radiation (W/m²)

Explanation: The formula calculates the amount of radiation that successfully transmits through a material based on its transmissivity property and the incident radiation intensity.

3. Importance of Transmitted Radiation Calculation

Details: Calculating transmitted radiation is crucial for various applications including optical systems design, solar energy analysis, radiation shielding, material characterization, and environmental radiation studies.

4. Using the Calculator

Tips: Enter transmissivity value (between 0-1) and incident radiation in W/m². Ensure both values are positive numbers with transmissivity not exceeding 1.

5. Frequently Asked Questions (FAQ)

Q1: What is the range of transmissivity values?
A: Transmissivity ranges from 0 (completely opaque) to 1 (completely transparent). Most materials have values between these extremes.

Q2: How does transmissivity relate to absorbance and reflectance?
A: For a given material: Transmissivity + Absorptivity + Reflectivity = 1, assuming no other energy interactions occur.

Q3: What factors affect transmissivity?
A: Material composition, thickness, wavelength of radiation, temperature, and surface conditions all influence transmissivity values.

Q4: Can transmissivity be greater than 1?
A: No, transmissivity is a dimensionless coefficient that cannot exceed 1, as it represents the fraction of incident radiation transmitted.

Q5: How is this calculation used in practical applications?
A: It's used in designing optical filters, calculating solar gain through windows, radiation protection systems, and various spectroscopic applications.
