EM Spectrum and waves

Front

What are electromagnetic waves with the longest wavelengths?

Back

Radio waves.

Front

How do you calculate the speed of a wave?

Back

Speed = Frequency × Wavelength.

Front

If a wave has a frequency of 50 Hz and a wavelength of 10 m, what is the speed of the wave?

Back

500 m/s.

Front

What is the relationship between frequency and energy?

Back

Frequency increases, energy increases.

Front

Which type of radiation has the longest wavelength?

Back

Radio waves.

Front

What is the formula to find the frequency of a wave?

Back

Frequency = Speed / Wavelength.

Front

If a wave has a wavelength of 10 m and a speed of 340 m/s, what is the frequency?

Back

34 Hz.

Front

What are gamma rays?

Back

High-energy electromagnetic waves with very short wavelengths.

Front

What are x-rays used for?

Back

Medical imaging to view inside the body.

Front

What is infrared radiation?

Back

Electromagnetic radiation with wavelengths longer than visible light but shorter than microwaves.
