Waves

Front

What is the wavelength for a quantum of light with energy of 7.56x10^-19J?

Back

2.62x10^-7m

Front

The blue section of the wave is measuring _________________.

Back

wavelength

Front

A light has a wavelength of 5.06x10^-7m. What is the frequency of the light? What is the color of light?

Back

5.93x10^14Hz, Green

Front

What is a wavelength?

Back

The distance from one wave crest to another.

Front

What does the letter 'h' represent in the formula E = hv?

Back

Planck's constant

Front

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

Back

v = fλ (speed = frequency x wavelength)

Front

What is the frequency of a wave with a wavelength of 3.00x10^-9m?

Back

Frequency = 1.00x10^16Hz (using v = c = 3.00x10^8m/s)

Front

What is the difference between a crest and a trough in a wave?

Back

Crest is the highest point, while trough is the lowest point of a wave.

Front

What is the relationship between frequency and wavelength?

Back

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

Front

What is the unit of frequency?

Back

Hertz (Hz)
