The will calculate the:

- Pressure of light when the intensity of light beam and the incident angle are known.

**Calculation Parameters:** Medium of propagation is assumed as vacuum

The power of light (P) is W [Watt] |

Power of light (P) calculation |
---|

P = ∙ (1 + r) ∙ cosI/c^{2}θP = ∙ (1 + /) ∙ cos()^{2}P = ∙ ∙ ^{2}P = ∙ ∙ P = |

Light Pressure Calculator Input Values |

Intensity of incident light (I) W/m^{2} [Watt per square metre] |

Coefficient of reflection (r) |

Angle of light incidence (θ) ° [degree] |

Speed of light (c) m/s [metre per second] |
