This video tutorial explores the relationship between frequency, wavelength, and the speed of light. It begins by defining frequency and its measurement, then examines the inverse relationship between frequency and wavelength. The speed of light is introduced as a constant, and the video derives the equation c = lambda nu, showing how wavelength and frequency relate to the speed of light. The tutorial highlights the beauty of mathematics in describing natural phenomena.

What symbol is used to represent frequency?

• Lambda

• Beta

• Alpha

• Nu

What is the relationship between frequency and wavelength?

• They are unrelated.

• They are the same.

• They are inversely proportional.

• They are directly proportional.

How is frequency measured?

• In meters per second

• In cycles per second

• In meters

• In seconds

What happens to frequency as wavelength decreases?

• Frequency decreases

• Frequency increases

• Frequency remains constant

• Frequency becomes zero

What is the unit of frequency?

• Meters

• Seconds

• Joules

• Hertz

What is the speed of light in meters per second?

• 3 x 10^8 m/s

• 3 x 10^7 m/s

• 3 x 10^9 m/s

• 3 x 10^6 m/s

What is the visible spectrum range in nanometers?

• 400 to 700 nm

• 100 to 400 nm

• 700 to 1000 nm

• 1000 to 1300 nm

What is the symbol for the speed of light?

• v

• c

• l

• f

What is the equation that relates speed of light, wavelength, and frequency?

• c = lambda / nu

• c = nu / lambda

• c = lambda + nu

• c = lambda * nu

Why is the speed of light always equal to wavelength times frequency?

• Because they are directly proportional

• Because they are inversely proportional

• Because the speed of light is constant

• Because they are unrelated
