What should Isla write in the areas marked A, B, and C?
2 answers:
Answer:
Radio waves: have a longer wavelength
X-rays: have a higher frequency
Both: they travel at the same speed
Explanation:
Missing part of the question:
"Isla made a diagram to compare x-rays and radio waves. what should isla write in the areas marked a, b, and c?"
X-rays and radio waves are both types of electromagnetic waves.
Electromagnetic waves consist of oscillations of the electric and the magnetic fields in a plane perpendicular to the direction of propagation the wave.
All electromagnetic waves travel in a vacuum always at the same speed, the speed of light:
Electromagnetic waves are also classified into 7 different types, according to their wavelength/frequency. From longest to shortest wavelength (and from lowest to highest frequency, since frequency is inversely proportional to wavelength), they are:
Radio waves (>1 m)
Microwaves (1 mm - 1 m)
Infrared (750 nm - 1 mm)
Visible light (380 nm - 750 nm)
Ultraviolet (10 nm - 380 nm)
X-rays (0.01 nm - 10 nm)
Gamma rays (<0.01 nm)
Therefore, the correct matches are:
Radio waves: have a longer wavelength
X-rays: have a higher frequency
Both: they travel at the same speed
