Which type of electromagnetic radiation has the longest wavelengths? Which type of electromagnetic radiation has the shortest wa

irinina [24]

Answer: Radio waves has the longest wavelength and Gamma rays has the shortage wavelength.

When wavelength increase and frequency decrease it is related to the energy of each type of radiation.

Explanation: The wavelength of Gamma rays is less than 10 pico meter and energy of Gamma rays is greater than 100kev while the wavelength of radiowaves is 100m to 100km and energy is 100ev to 100kev.

Energy is inversely proportional to wavelength so Gamma rays which have shortage wavelength will have highest energy and radio waves which have longest wavelength will have minimum energy

E=hc/wavelength

The equations of the tangent to the curve y=xsinx at the point (pi/2,pi/2) is

never [62]

The first thing you have to realize is that tangent is the slope of a curve on a given point. You can solve for the slope by finding the derivative of the given function. So:

$\frac{d}{dx} xsin(x)$

Next use product rule (I recommend watching videos if you're confused):

$= [sin(x)] + [x*cos(x)]$

Next substitute you x-value (π/2) into your derivative:

$= [sin( \frac{ \pi}{2} )] +[ \frac{\pi}{2}*cos( \frac{\pi}{2})]$
$= 1 + \frac{\pi}{2} *0$
$= 1$

So our slope at π/2 is 1. Next we use our slope-form and substitute our given value and solve for y-intercept (algebra-stuff)

$( \frac{\pi}{2}) = 1( \frac{\pi}{2}) + b$
$b = 0$

So we get our equation:

$y = x$

So our answer is E
