A TV satellite broadcasts at a frequency of 5000 MHz, (1 MHz = 1 million Hertz). What is the wavelength of this radiation?

The wavelength of this radiation is 0.06 m.

Explanation:

Given that,

Frequency = 5000 MHz

We know that,

Speed of light

We need to calculate the wavelength of this radiation

Using formula of wavelength

Where, = wavelength

= frequency

c = speed of light

Put the value into the formula

Hence, The wavelength of this radiation is 0.06 m.

here we know that ball will drop down by total distance 3.2 m

so here we know that

now using kinematics

now in the same time it will cover horizontal distance of 0.75 m

so speed of the ball will be
