Q: A student says that the two terms speed and frequency of the wave refer to the same thing. What is your response?
Ans: As we know that speed is defined as the rate of distance.
           V=d/t and its unit is m/s
And 
Frequency is defined as the number of vibrations completed in one second.
    f=1/T
its unit is hertz.

Therefore, both are different.

They are related:

v=ƒƛ

Further Descriptive Explanation:

Speed and frequency are two different characteristics of a wave. Speed refers to how fast a wave travels through a medium, such as the speed of sound through air or the speed of light through a vacuum. Frequency, on the other hand, refers to how often a wave oscillates or vibrates within a certain period of time. It is typically measured in cycles per second, or hertz (Hz).

For example, a sound wave with a high frequency will have a high pitch, while a sound wave with a low frequency will have a low pitch. The speed of sound waves through the air is relatively constant, but the frequency can vary. On the other hand, the speed of light is always constant, but the frequency can vary, resulting in different colours of light.

In summary, speed and frequency are different aspects of a wave and should not be confused with one another.
