Answer: Radio waves. Next longer is visible, ultraviolet, and shortest is x-rays.
Step-by-step explanation:
Just a fact. Radio waves also have the lowest energy and frequency. This is a physics question.
Wavelength = speed of light/frequency
Meters = meters per second / Hertz
= meters / second × seconds
Energy = Planck's constant times frequency.
Answer:
x²+x-30
x=5
Step-by-step explanation:
The equation is
(x+3+x-1)/2 × x=30
x²+x-30 (it's the quadratic equation)
x²+6x-5x-30=0
x(x+6)-5(x+6)=0
(x+6)(x-5)=0
x=-6
x=5
It's impossible for Length to be negative
So x=5
