What is emission spectra and its types? Each source has its own characteristic emission spectrum. The emission spectrum can be divided into three types: (i) Continuous emission spectra (or continuous spectra) if the light from incandescent lamp (filament bulb ) is allowed to pass through prism (simplest spectroscope ), it splits into seven colours. What […]

They will even venture onto land to find prey. Why do crocodiles cry fake tears? Crocodile tears (or superficial sympathy) is a false, insincere […]
What is energy type signal?
What is energy type signal? A signal can be categorized into energy signal or power signal: An energy signal has a finite energy, 0 < E < ∞. In other words, energy signals have values only in the limited time duration. For example, a signal having only one square pulse is energy signal. For example, […]

Why is derating necessary?
Why is derating necessary? Derating increases the margin of safety between part design limits and applied stresses, thereby providing extra protection for the part. By applying derating in an electrical or electronic component, its degradation rate is reduced. The reliability and life expectancy are improved. How do you calculate derating current? Selection of cable – […]

What is used to measure plate movement?
What is used to measure plate movement? – How do scientists measure the distance that plates move? – Scientists use GPS satellites and laser technology to measure the plates movements down to the centimeter. – Laser pulses are shot from the ground to a satellite to determine the exact location of the plates. What techniques […]
