☆☆☆☆☆A real machine is like an ideal machine in that there are no massless chains or frictionless bearings. The parts of an ideal machine are rigid and weightless.
The characteristics of a sound wave is the Amplitude, Frequency, Wavelength, time period, and velocity. The sound wave itself is a longitudinal wave that shows the rarefactions and compressions of a sound wave.
The light reflects or refracts on hitting the medium.
false, the set of natural numbers does not include 0, which can be considered a whole number.
No, light is a transverse wave.
No, light is a transverse wave.
No, light is a transverse wave.
No, light is a transverse wave.
Wave speed = wavelength x frequency
4.0 m/s = wavelength x 2.50 Hz
1.6 m = wavelength
Kelvins are the SI units of Temperature.
Constructive interference occurs when amplitudes of two waves combine to produce a wave with a larger amplitude.
If a wave with a smaller amplitude is produced, destructive interference has occurred.
true
Radiation is a form of electromagnetic energy, the light as we saw is part of the whole electromagnetic spectrum of around 400 - 700 nm. When we generally speak of electromagnetic wave length we usually refer to radio to microwave of wavelength around 10-2 to 103 m but the whole span of wavelength from gamma ray to radio wave counted as electromagnetic wave.
Period = 1/Frequency = 0.00175 seconds (approx)
Period = 1/Frequency = 0.00175 seconds (approx)
Period = 1/Frequency = 0.00175 seconds (approx)
Period = 1/Frequency = 0.00175 seconds (approx)
words like “violence“ and “bloodshed” give the excerpt a threatening tone
