Answer: short wavelength, high frequency
Explanation:
Gamma rays are highly energetic electromagnetic waves. High energy implies high frequency.
E = h ν
h is the Planck's constant, ν is the frequency.
For electromagnetic radiation, frequency is inversely proportional to wavelength. Thus, gamma rays have high frequency but short wavelength.
The frequency of gamma rays is greater than 10¹⁹ Hz and wavelength is less 10⁻¹² m.
Answer:
D). energy resulting from the attraction between two masses.
Explanation:
Answer:
v = 22.54 mph.
Explanation:
Given that,
Distance moved, d = 200 m
Time, t = 19.8 s
We need to find the runner's average speed.
We know that,
1 mile = 1609.34 m
200 m = 0.124 miles
19.8 seconds = 0.0055 h
So,
Speed = distance/time
So, the runner's average speed is 22.54 mph.
Answer:
The speed of light changes as it moves between media. This causes refraction. Angles of refraction can be calculated using known speeds or wavelengths. Beyond the critical angle, light is reflected.
