MISA Waves and Electromagnetic Radiation

Question 1

What is the relationship between the frequency and wavelength of an electromagnetic wave?

Accepted Answer

They are inversely proportional — higher frequency means shorter wavelength

Answer

They are directly proportional — higher frequency means longer wavelength

Answer

They are independent of each other

Answer

They are equal when measured in the same units

Question 2

Question 5

Which color of visible light has the longest wavelength?

Accepted Answer

Red

Answer

Violet

Answer

Green

Answer

Blue

Question 6

What happens to the speed of light when it passes from air into water?

Accepted Answer

It decreases because water is denser

Answer

It increases because water is denser

Answer

It remains the same in all transparent media

Answer

It increases because water has a lower refractive index than air
