Which electromagnetic waves have the shortest wavelengths and highest frequencies?
Usimov [2.4K]

Answer: Gamma rays

Explanation: The given waves belong to the electromagnetic spectrum which consists of different electromagnetic radiations arranged in terms of increasing wavelengths or decreasing frequencies.

E= h\times \nu

\nu=\frac{c}{\lambda}

Thus E=\frac{h\times c}{\lambda}

E= energy

\nu= frequency

c = speed of light

\lambda = wavelength

Thus frequency and wavelength are inversely related. The waves having high energies ave high frequencies and have shorter wavelengths.

Thus gamma rays having highest energy have highest frequency and shortest wavelength.

masha68 [24]

ThermalThermal  relief valve installed in a Hydraulic system will have the highest pressure setting.

<h3>What is the hydraulic system? What are the types of hydraulic systems ? </h3>

Hydraulic system function and perform tasks through using a fluid that is pressurized . There are two types of hydraulic systems open loop hydraulic systems and closed loop hydraulic system . In open loop ,when the actuating mechanism is idle ,there will be fluid flow but no pressure.

Closed loop system use an additional pump called charge pump or feed pump.

Thermal relief valve is Designed to protect the pump and operators in circumstances when the pump is running and the discharge outlets have been closed .
