All waves in the electromagnetic spectrum travel at the same speed through a vacuum, but differ in their frequency and wavelength. a wave with a long (large) wavelength will have a low frequency.
What is an electromagnetic spectrum ?
The span of electromagnetic radiation's frequencies, as well as the associated photon energies and wavelengths, is called electromagnetic spectrum.
Define frequency and wavelength.
The relationship between speed and wavelength is known as frequency. The ratio of speed to frequency is referred to as the wavelength in contrast. Waves of audible sound have a frequency range of 20 to 20 kHz. The wavelength of visible light, on the other hand, is between 400 and 700 nm.

Yes because if they are further away it makes it hard for them to attract each other
Answer:
Blue litmus paper remains blue
Solution is basic
Explanation:
Blue litmus paper turns red when a solution is acidic while the red litmus paper turns blue when a solution is alkaline. In this case, Cassandra observed that red litmus paper turned blue, a clear indicator that the solution is alkaline. Similarly, when using blue litmus paper, the color remains blue for the same solution since it's basic.
Answer:
0 m/s
Explanation:
Average velocity of an object is given by the net displacement divided by time taken. Displacement is equal to the shortest path covered by the object.
In this problem, a player runs the length of the 30-meter court and back. The player does this three times in 60 seconds.
As the player runs the court and returns to the original point. It would mean that the shortest path covered is 0.
Average velocity = displacement/time
v=0/30
v = 0 m/s
Hence, the correct option is (1).
