What is the wavelength of a wave that has a speed of 3 km/s and a frequency of 12 Hz? A. 36 km B. 3.6 km C. 0.25 km D. 4 km

butalik [34]

Answer:

c. 0.25km

Explanation:

v=f x wavelength

3000 = 12 x wavelength

wavelength = 3000/12 = 250m

250m to km

To convert m to km, we divide by 1000

250/1000 =0.25km

wavelength = 0.25km

Time period of a simple pendulum is measured at Karachi. What change will occur in the time period, if it is measured on mount e

Reil [10]

The period of a pendulum is given by $T=2 \pi \sqrt{ \frac{l}{g} }$
since Karachi is near sea level, g is larger than it is on Mt. Everest. That means the pendulum will have a larger period on Mt. Everest than it would in Karachi.

What is the speed of an electromagnetic wave with a frequency of 100 mhz as it travels through a vacuum?

SCORPION-xisa [38]

Answer:

The speed of the wave with a frequency 100 mhz will be $3\times 10^{8}m/sec$

Explanation:

We have given that frequency of light is 100 mhz

We have to find the speed of light in vaccuum

We know that all electromagnetic waves travels in vaccum wth the same speed as the speed of light

And we know that speed of light is equal to $3\times 10^{8}m/sec$

So the speed of the wave with a frequency 100 mhz will be $3\times 10^{8}m/sec$
