What is the full form of spot?

“Satellite for observation of Earth”) is a commercial high-resolution optical Earth imaging satellite system operating from space.

What kind of satellite is IKONOS?

commercial Earth observation satellite
IKONOS was a commercial Earth observation satellite, and was the first to collect publicly available high-resolution imagery at 1- and 4-meter resolution.

How to calculate the wavelength to frequency?

Frequency is denoted by f or ν and is calculated in the units of Hertz. As we know, for a sinusoidal wave moving at a fixed speed, the wavelength of the wave is inversely proportional to its frequency. Calculate the wavelength to frequency using BYJU’S online calculator. The Formula for Wavelength to Frequency

What is the frequency of the light wave?

The frequency of the wave is equal to 6×10 -4 Hz. Example 2 For a light ray having a wavelength equal to 200 nm, calculate the frequency. Solution: Given, the wavelength of the light ray = 200 nm.

What are the differences between rfrf and spot 4?

RF communications: Onboard solid-state recording capacity of 90 Gbit (EOL). The onboard memory can store 550 images, compared to 400 on SPOT 4. Although the magnetic recorders provided more capacity (120 Gbit), the file management system allocates available storage capacity more efficiently.

How to find the frequency of a photon particle?

Solution: Given, the wavelength of the photon particle = 500 nm. In order to calculate the frequency of the photon particle, we use the formula given above. The frequency of the wave is equal to 6×10 -4 Hz. Example 2 For a light ray having a wavelength equal to 200 nm, calculate the frequency.
