HPS Flashcard 5.1 Waves

Front

What is the energy of light with a wavelength of 4.06 x 10^-11 m?

Back

4.90 x 10^-15 J

Front

What is the speed of light?

Back

3.0 x 10^8 m/s

Front

What is the measurement between points D and E called?

Back

Amplitude

Front

What are points D and H in a wave?

Back

Troughs

Front

What is Planck's Constant?

Back

6.625 x 10^-34 Js

Front

Define wavelength.

Back

The distance between successive crests of a wave.

Front

What is frequency?

Back

The number of waves that pass a point in one second.

Front

What is the formula to calculate the speed of a wave?

Back

Speed = Wavelength x Frequency

Front

What is the relationship between wavelength and frequency?

Back

They are inversely proportional; as wavelength increases, frequency decreases.

Front

What is amplitude in a wave?

Back

The maximum distance from the rest position to a crest or trough.
