In this paper, the frequency drift rate of solar radio bursts (type III) is considered for the case . Many studies have shown that, under the distance condition specified above, the electron density of the solar corona is related to . For type III radio bursts, using the relationship between the radiation frequency and the electron density of the surrounding medium , it is shown that for the case it is equal to . If we use empirical formulas for the electron density, which are well satisfied under the condition , then in most cases it is equal to . Most studies refer to the ratio . For comparison, the frequency drift rate changes by a factor of v0.16.
