6B Waves

Front

What happens to the energy of an electromagnetic wave if its wavelength is longer?

Back

Energy is lower.

Front

What is the formula to calculate frequency from wavelength?

Back

C = λ x ν

Front

If a wave has a large wavelength, what can be said about its frequency and energy?

Back

It has a low frequency and low energy.

Front

What type of relationship exists between frequency and energy?

Back

Direct relationship.

Front

What is the definition of wavelength?

Back

The distance between one point of a wave to the same point on the next wave.

Front

What is the unit of frequency?

Back

Hertz (Hz).

Front

How is the speed of a wave calculated?

Back

Speed = Wavelength x Frequency.

Front

What is the relationship between wavelength and frequency in electromagnetic waves?

Back

As wavelength increases, frequency decreases.

Front

What is amplitude in the context of waves?

Back

The maximum displacement of points on a wave from its rest position.

Front

What is the frequency of a wave with a wavelength of 2 meters if the speed of the wave is 340 m/s?

Back

Frequency = Speed / Wavelength = 170 Hz.
