Answer:
The beam of red light contains more photons
Explanation:
The energy of a photon is directly proportional to its frequency:
where
h is the Planck constant
f is the frequency of the photon
In the electromagnetic spectrum, red light has longer wavelength than blue light: this means that red light has lower frequency than blue light (because frequency and wavelength are inversely proportional to each other). So, this means that one photon of red ligth has less energy than a single photon of blue light. Therefore, in order to have two beams with same energy, the beam of red light must contain more photons than the beam of blue light.
Complete Question
A radio technician measures the frequency of an AM radio transmitter. The frequency is 14603 kHz . What is the frequency in megahertz? Write your answer as a decimal.
Answer:
The value is
Explanation:
From the question we are told that
The frequency is
Generally
=>
=>
here we will use the concept of Newton's III law
as per Newton's III law the impulse given to the ball is same as the impulse lost by the bat
So here we will say
impulse gain by the ball = impulse lost by the bat
given that
For ball the change in speed will be
now from above equation
so speed of bat will decrease by 6.72 mph
