Answer: (1) 5.0 x 10^ -10 s
Explanation:
1.5 x 10^-1 m / 3 x 10^8 = .5 x 10^-9
= 5 x 10^-10
The time period of the wave will be 5.0 x 10⁻¹⁰ sec. The time period is the period of one oscillation of a wave.
The period is the amount of time it takes for a wave to perform one full oscillation. T is the symbol for it. Taking the reciprocal of the frequency yields the frequency of the oscillation.
The given data in the problem is;
[tex]\rm \lambda[/tex] is the wavelength of electromagnetic wave=1.5 × 10⁻¹meter
T is the period of this wave =?
c is the speed of light = 3×10⁸ m/sec
The relation between the wavelength, speed, and the time is found as;
[tex]\rm \lambda= \frac{c}{f} \\\\ f=\frac{1}{T} \\\\ \rm \lambda= c \times T \\\\ \rm T=\frac{\lambda}{C} \\\\ \rm T=\frac{1.5 \times 10^{-1}}{3 \times 10^8} \\\\ T=5 \times 10^{-10}[/tex]
Hence the time period of the wave will be 5.0 x 10⁻¹⁰ sec.
