light that has a frequency of 1.5 x 1015 Hz.
It would help if you proofread your questions before you posted them.
Online, “*” is used to indicate multiplication to avoid confusion with “x” as an unknown.
Online "^" is used to indicate an exponent, e.g., x^2 = x squared.
f = 1.5(what?) * 10^15

To understand the light that has a frequency of 1.5 x 10^15 Hz, let's break it down into two parts: the frequency and the unit used to measure it.
Frequency is a fundamental property of waves and is defined as the number of occurrences of a repeating event per unit of time. In the case of light, frequency represents the number of oscillations of an electromagnetic wave that occur in one second.
In the metric system, frequency is typically measured in units called Hertz (Hz), named after the German physicist Heinrich Hertz. One Hertz represents one cycle per second, which means that a light wave with a frequency of 1 Hz completes one full oscillation every second.
Now, let's focus on the specific frequency mentioned: 1.5 x 10^15 Hz.
To understand this value, we need to use scientific notation. The "x 10^15" part indicates that we have 1.5 multiplied by 10 raised to the power of 15. This means that we move the decimal point 15 places to the right, giving us a very large number.
Therefore, a light wave with a frequency of 1.5 x 10^15 Hz completes 1.5 x 10^15 oscillations or cycles per second. This frequency is in the range of extremely high-energy electromagnetic waves, such as X-rays and gamma rays, which have frequencies even higher than visible light.
